If you got on well with the Boss upgrade to the Gt100core it really is ridiculously good, can be for a steal secondhand.
You can set it up as if it's just individual pedals you turn on and off with the three foot switches, or program it to do a whole set list with patches. The hardware is newer than the stomp which will likely see a replacement model come out in a few years time.
It's not better than the stomp it's just different and easily as good.
The only reason I would say not to get it is if you're after recreations of lots of different amps or pedals. If that's your thing go neural or line 6.
If you like Boss effects however (they were THE standard effects pedal for decades for a reason) go boss.
