Agilent & Rigol have the same Screen Resolution, Agilent .5" bigger 800x480.
Siglent CFL, BK Precision 2556 & Tek DPO2022B have similar or the same 7" screen 480x234 resolution, 64K Color Display.
Owon SDS8202 & Instek GDS2202A have same 8" 800x600 Display resolution.
UNI-T UTD-4202C & LeCroy WaveAce 221 have the smallest 5.7" screen size, LeCroy 222 has 320x240, the Uni-T is Unknown, but probably the same.
Owon MSO 7.8" 640×480 pixels, has a 3rd Place in this shotout, LeCroy 322A, Hameg same resolution, but LeCroy has 7.5" and R&S Hameg has 6.5".

Both Rigol & Agilent have the same wfm/s 50.000 ("2nd place")
Instek has 1st Place true >80.000wfm/s.
Tektronik DPO has 3rd Place, LeCroy WaveJet 322A has 4th Place, and R&S Hameg the 5th Place.
According to Dave Owon SDS Review, the SDS9302 has 35wfm/s, Uni-T, Siglent CFL & BK Precision are Unknown...

Rigol has most sensittive Vertical/div .5mV, Instek has 2nd Place 1mV, most others have 2mV "3rd Place."***

Instek has Segmented Memory, Agilent is optional +$307usd.
Higher Price seems directly proportional to a lower/stable ppm.
Rigol has the 1st Place in Memory, Owon SDS8202 2nd Place, Owon MSO8202T 3rd Place, Instek, Tek DPO, R&S Hameg share 4th place with 2Mpoints/channel, Uni-T 5th place if web specifications are right*, Agilent 6th place* but can be upgraded to a 5th place 1M memory +$200usd, LeCroy 322A has 5th place 500kpoints/ch, Siglent & BK Precision sharing the 6th Place 24Kpts, LeCroy WaveAce222 9kpts has 7th place, Tek TDS 2.5k has the last Place.

Question is: Segmented Memore could rival Rigols Big Memory?
Memory is that important?
When Memory becomes important?
Memory vs. wfm/s ? wfm/s wins most of the times.

Less Buggy software/Firmware?

Agilent, Instek, Tek DPO & Rigol have some kind of Analog Intensity Graded Display, Owon maybe, the others are unknown,

There you go then. That's a pretty comprehensive rundown.

You find Siglent price perhaps from one of worlds most expensive place.

(without EU taxes etc)
SDS1202CFL is more like well under 1k$ and note (look carefully if BK model is different or not technically - who made it?)
SDS1204CFL is 4 channel and also its price is around 1k$
SDS1304CFL is 4 channel 300MHz model and even it can normally buy under 1.5k$
With 1795USD price  you can buy bundled SDS1202CFL + SDG5000
With 4 channel models you get 2 full 2GSa/s channels if only 2 channel is in use.
For 2 channel models one channel in use 2GSa/s and with 2 channel in use 1GSa/s per channel.
CFL models have LAN as default.
