Both can be answered by someone who works with all of the mentioned scopes - And then it´s his own impression.
In my case, I got following "scope owning history":
- Rigol DS1000Z
- Rigol DS2000
- Siglent SDS1104X-E
- Rigol MSO5000
- Siglent SDS2000Xplus
- Siglent SDS2000X HD (actual scope)
GW Instek never came into my mind, maybe they making good scopes and nearly nobody knows about, or they knowing about it and this may explain their place by the hobbyists. ;)

Interesting. Two questions:
1. Why did you switch from the 2K plus to the 2K HD?
2. How did the MSO5K compare with the SDS1104X-E *purely in terms of noise and OS/UI quickness*?
Thanks.

Feature set and specs determine what one can do with any instrument not how fast it can do it.

True, but it's not exactly about analyzing a circuit in five minutes vs. (say) seven.
It's about how much responsive the instrument is. If you read the threads here and there, users with slow scopes are pretty pissed off, and, by my limited experience, with good reason.
I bought that crappy Hantek a while ago. Slow and laggy as hell. Returned.
Bought as a temporary solution an Owon HDS242s handheld (it costs just 167 eur and I needed a scope). It's like 10X more responsive. I mean, it's a very limited machine, but you can work with it, whereas you couldn't with the Hantek (*).
That's what I meant by 'fast'.

GW Instek never came into my mind... same here but due to lack of other interesting models I tried a GDS-2204E nevertheless (with very explicitely requiring to be able to return the oscilloscope) and got a very pleasant surprise. I use the GW Instek regulary besides the higher end R&S oscilloscope that is also on my desk.

Faster means an instrument is more efficient and more enjoyable to use. So yes, being able to make measurements fast is a good feature. But it is missing from datasheets and specs. Reading specs is like judging a book by the cover. You still don't know whether you'll enjoy the book. You either have to read the book or go by the reviews (which might be skewed).
I used to own an Agilent MSO7104A (4 channel 1GHz + 16 channel MSO) which IIRC costed like $20k when new. It required endless dicking around with knobs and going through deep menus in order to configure things like decoding or math. The GW Instek GDS-2204E I bought later on was such a relief compared to the MSO7104A. The MSO7104A is long gone but I still have the GDS-2204E because it is such a pleasant oscilloscope to use.

All Siglent DSO's capable of Bode plot

Apart from the bode plots, if you had to make a case for the Siglent scope vs. the Instek, what would you say to a prospective customer?
What does your scope have that the Instek lacks?
--- End quote ---
Many things.
It has 2 1GS/S ADC instead of one. It has more display modes. It has better vertical sensitivity. Web control.
Nico owns GW Instek scope, but a 2000E series that is nice little scope but much more expensive.
GDS1054 has some thing going for it and it is better than, say, Rigol DS1054, but not SDS1104X-E.
Truth to be told, I have been following discussion here and I think you might be expecting too much from a price range you are prepared to pay for. I don't think GDS1054 will carry you for years. Neither the AD2 is what you might expect it to be..
Excuse me for being blunt, but you seem to be asking unusual questions and seem to more be arguing and inciting adversarial discussion than really trying to get good information which will help you decide what equipment would be good for your use case..
And for some time now discussion has been going in circles...
You don't want to read datasheets but UI responsiveness is important. An intuitiveness, whatever that means..
You have no set application target.
You are a beginner and this is your first scope.
And then you want sophisticated scope although there will be years before you need anything more sophisticated than either GDS1054, Rigol DS1054, SDS1104X-E.
AD2 is not really "good" for digital except very slow stuf.
You cannot combine AD2 and any other scope with a software. It doesn't work that way..
Again, sorry for being direct. But my opinion that for a beginner you should start with any of the mentioned scopes. If this is a hobby maybe you will lose interest. If you are doing this long term and or pro you will need many thousands € for equipment in coming years..
If I were in your place I would either buy SDS1104X-E and SDG1000X AWG for more analog minded application or a MSO5000 if you are going to predominantly do microcontrollers robotics, motor control and such.
First option gives you great little scope and a 2ch real AWG and Bode plot that works really well. MSO5000 is not really good for hardcore analog stuff but has proper MSO integration and it also has 2CH AWG although very limited in amplitude and features.
If you overgrow any of mentioned equipment you will easily sell it and move on to better stuff.. Or keep it for reserve or whatever..
