It all depends what it is that you're looking to do with it. Running off road, primarily pretty close to blinky, I'd guess that there are a lot of speedos that will be "OK".
However, 18 months or so ago, I was asked to do some speedo testing for a manufacture / distributor who was looking at introduce an ESC. It came from one of the bigger OEM companies in China, and there is no doubt that it "took inspiration" from Hobbywing v3.1 (It wasn't one of the 4/5 Sky RC speedos that are available from different brands!!). All I can say, is running modified touring car outdoors it needed a bit of work!! The power delivery wasn't pretty, it would light up wheels pretty much when ever you wanted to. On the one hand you could say "wow" look at the power it has, but on the other hand there was no doubt that the lack of finesse was making it slower around the track.
I did this testing comparing this ESC against Hobbywing v3.1 and Much More Fleta Pro - and honestly both of those were night and day ahead.
I haven't seen any clone ESC's that will run any of Hobbywing's V3 and above software, just that from the v2 - which would have stopped development 5-6 years ago.
