As far as production cues, I think that all companies make a cue that just doesn't quite cut it and some that just seem great. I personally own cues that range from a couple hundred to a couple thousand. Yes, my Mezz LE 2000 is, for me, an exceptional cue that just feels right and natural. Everything about it seems to fit my style of play and has never once disappointed me. By the same token, I have a Cuetec Earl Strickland ($125) with and extreme taper wood shaft, that I've never had a problem running a table with. I've always liked McDermott and Joss. Some were great and some weren't worth the trouble of throwing away. Generally speaking, the more it costs, the higher the quality and workmanship. However, that doesn't necessarily mean that the higher the cost, the better the cue. I've heard bad things about most cue companies, but I've also known people that use those same cues and can knock the eyes out. I've also seen people with high dollar custom cues that should probably stick with hopscotch.
One of my best friends shoots with a Schon STL-17. Another friend routinely beats him with a Lucasi house cue. I think that if you stay with a known company and find the cue that suits you personally, it's hard to go wrong. Again, I'm speaking strictly of mass production cue companies, not custom cue makers. Either way, even with custom cues, it comes down to you and your game, personally.
