I use both kinds very frequently so I can comment on this. The main difference is that SLA strength is more uniform and FDM strength is very directional.

And the strength of the output is highly dependent on the material for both printers. The typical resin is extremely brittle, but rather heat resistant. But you can get flexible or tough material which are both less brittle but also less rigid.

So to answer your question: not necessarily :) nylon-like SLA materials are pretty good for usable everyday items if you don't mind the slight fidelity losses (still better than FDM)
