Sure, but that's not obligatory. You can have 8Gsa/S when you really need it.

That's my point, if needed the Rigol can satisfy 8Gsa/s! Others costs more and with less feature (eg Rigol have also Function Generator built in)

8GSa/s on a scope without 50R inputs seems somewhat pointless, but the minimum 2GSa/s (4 channels active) with 350MHz BW does mean that it will be much less likely to have aliasing effects.  I doubt that is a serious issue for you, but that's the only real selling point.  I'm all for more samples, but not at the expense of some of the other things the Rigol does not do as well.

How about HDO1000?

Speaking of which - if the way my Siglent SDS1104X-E operates is representative of how modern DSO's work, the scope cuts back on sampling frequency at lower timebases...  So if the you don't really work with high frequencies much, wouldn't you be paying for sampling rates you couldn't use?

I'm with Nico here..

This is same again for thousand time same question that was answered so many times before.
To OP:
what do you expect new to hear?  It has been discussed to death..

In that approximate range of MSO scopes there are two scopes Rigol MSO5000 and Siglent SDS2000XPlus.

Rigol is a bit cheaper and Siglent is a bit more expensive. MSO5000 will do the job if you don't need absolutely best analog performance and has few more things: one AWG output  more, more math channels and more decode channels. AWG is limited on both (separate AWG is really the way to go) and math and decode usefulness depends on what you do.
Siglent has better sensitivity and much lower noise, propper FFT implementation, excellent Bode plot implementation, it has only 2 math channels but those you can type arbitrary formula... etc. Each has specific set of strengths and weakneses.

Siglent is generally more refined. To many people MSO5000 will be sufficient. And so will be DS1054Z or Siglent SDS1000X-E..

My advice is to find one of previous endless discussion on this and do your homework. Nobody here actually know what you want, expect, or will do in a future. And it is boring to repeat all the same stuff again and again. Most of the people that could be helpful don't even bother to answer anymore...
Good luck in your quest..
