Should I buy a Rigol MSO5000?

If sales aren't what they are expecting then bug fixes will be slower or they might even abandon it. Time will tell but be honest: do you want to take that chance? Can you postpone buying a piece of equipment you need now by several years? Or put differently: do you want to buy a product which doesn't do what it is specified to do but you might find out when it is too late? There is a reason why I tested the crap out of the GDS2204E: I wanted to be sure it wouldn't throw me a nasty surprise at the worst possible moment like the Siglent SDS2000 did.

What you went trough with Siglent was bad. They screwed you bad, and you are right to be mad. But even Siglent made a lot of improvement in that area. But I agree with you that people need to be cautious.  If they need instrument they have to heavily depend on, they should test right know if instrument does what they need right now. I don't care about promises if I need it NOW.

But that is applicable to every manufacturer. I didn't ( and I advise anybody not to ) buy R&S RTM3000 because it doesn't have basic search on segmented memory and on  such basic protocols as UART, I2C and SPI... You get 400 Msamples worth of I2C in 5000 segments and than you are supposed to go manually trough all them to find a single packet there..
I would like to meet an idiot who thought that was good idea.

So I got Keysight 3000T that has pathetic memory but at least everything works and is a pleasure to work with.
But it is so stable and bug free not because Keysight is God given.. No, it is good because it is almost 10 years old platform that was being debugged all this time. It's revision history is also full of bugs and it's 27 pages long... Result?  Reliable instrument.
But if I need long sample memory, I have to use my Picoscope.  But that is OK, no single instrument can do it all..

3000T also have stupid things:
. there are no histogram measurements. MSO5000 has it..
. you can count pulses only on analog channels, but not on digital where you need it more.
. hardware decode is great for speed. But you cannot apply and/or change decodes afterwards. So you cant just capture something and fiddle with settings until you setup it all right. You have to keep a running captures until you are happy with setting and than capture one you need. Which sometimes you can't do. In which cases software decodes are better. Cue in Picoscope...
etc.

Nobody is perfect.

All that was bad was no timely fix for issues Nico identified and he wasn't prepared to wait for them to arrive.
I get that frustration ^ and the ongoing mentions by Nico  :horse: of his early experience with Siglent has been partly responsible for a significant change in culture.

Exactly.

No scope is perfect. We will never see one that is.

In the area of digital scopes LeCroy is the definition of perfect, because they started building them about 40 years ago, when nobody else except HP had the faintest clue what a DSO could be.
When you think you need a car, but you can't afford a new one, you try to get a used one that fits. The recommendation to buy a bicycle instead is ridiculous. Especially if you already had a bicycle.

OT: Three months ago i happened to recap the power supply of our LeCroy 9354A. It is connected to a PC via GPIB and produces TIFF files with  colored traces on the press of a button. When we bought it 10 years ago it came fully equipped with software options. It does not decode serial data streams though. Those scopes currently sell for about US$ 600. The 1 GHz version would be 9374 or 9384.
Our 9354A has a trickle charger for the clock battery, so we can leave it off for years and it will turn on. It also got quiet fans. And it got two 1 GHz active probes.

Noy:
The handling/useability of  LeCroy is so uncommon many people doesn't like it.
We have a "old" DPO 7254 and a "new"  SDA820Zi-A beside some smaller Hameg/Tektronix and some everyday / everybench 1054z Rigols (enough to check powerup sequences / switching regulator / Low Speed stuff ) use and nearly everyone tries to measure most Highspeed things with the DPO because the handling is much more intuitive then the LeCroy..

Especially the active probes from LeCroy are worse. This tiny fiddly probes with their lego stuff and the tiny resistors you have to solder to your highspeed lines and these resistors are "unsolderable" they won't hold.. Just sneeze beside them and they are Off again... Crap!!!

Says who? Many people in that situation choose to buy a smaller car and accept the fact that they don't have leather seats and can't fit a sofa in the back.

Buying an old banger just in case they might go into the removals business one day just leads to higher maintenance bills and a smell of old dust every time they get in it.
