I grafted 10 trees on G210 last year & it was very difficult/ frustrating as it was very knobby, hard and small to graft.
I won’t use that again in my N TX zone 8 orchard. They seem to be brittle, a graft broke off in the Winter, that’s a long time after being grafted in March.
As far as performance, so far, they seem to be growing well so if you purchased a tree, it may be fine. I like G890 rootstock for my hot region. Good luck & happy growing.
