the xy-2 is simply an ender 3 clone.
My opinions on this should be clear - don't buy one :-)

However if you are looking at the x5sa pro - then in the same price range is the prusa mini.
smaller print volume but top of the range electronics and mechanics.
Worth considering.
From reports and looking at the specifications the NEW model of the tronxy x5sa pro is a decent machine.
The original model - not so much.
most plastic parts have been replaced with metal, the extuder and hot end has been upgraded - as has an awful lot of other things.
