I think it makes little sense to declare what is "best", as there is no such thing, only more or less appropriate for a given situation.
It would probably be more interesting to show the widest variety of what's available within that budget.
e.g. highest bandwidth 2-channel, most channels (analogue+digital), most protocol decoding, portable , PC-based, biggest screen etc.
That all comes out in the wash in the spreadsheet.
The BEST title gets the clicks
Well, then if the best title gets the clicks, just title it "
OSCILLOSCOPE DEATHMATCH 2022" and put lots of 🔥 emojis in the title. That'll get the kids a-clickin'.
Seriously, though, I would be looking for things based on feature list. 2-channel, 4-channel, DSO, MSO, memory depth, in-built decoding, etc.
