W3 Total Cache took sometime tuning it up but worth it for my customers. Most of issues I have seen or heard comes with issues with other plugins. The better plugins will tell you their rules to be able to play with W3T nicely. I use GtMetrix to help provide objective base to tune against. W3T also allows us to avoid having multiple plugins as long as you get the tuning correct. No 5 star due to support structure.
