Best Expert Builder for MT5/4

Guys could you please tell me the best expert builder for MT4/5 which hasn't got many bugs???? I suck at coding and would like help building experts. I am currently using fxdreema and I have noticed a few bugs tbh.

thanks for your advice.

P.S.

are expert builders even worth using??? are there any downsides to building experts and optimising them instead of coding them??
