I like it. I feel it's about the right size and the texture/precision is good. It's a bit smaller than my 2014 rMBP which I thought was fine too.
On the other hand, the new MBPs have these comically massive trackpads which also scared me away. Less room to rest your palm, lots of accidental clicks, etc.
Overall, I don't think about it which probably means it's good. There's also the optional trackpoint/nub. I use it occasionally for fun, but I'm not a fanatic about it yet. Nice to know it's there, I guess? Might be handy for some kinds of games on the go.
