I probably purchased 90% of my tools from Avery, 9% from Cleaveland, and the remaining 1% from a variety of vendors that I only purchased a single item.
Both Bob and Mike run great companies and sell quality tools. On a tool by tool basis, one may be slightly better than the other. The simpliest thing to do is to by a complete kit from either.
Based upon some input from local builder's I ordered most of the Avery kit and suplemented it with tools from Cleaveland. After six months of use, there are a few things that I would have probably done differently if buying today.
I haven't had the opportunity to deal personally with Mike, but I've heard nothing but positive comments. I have dealt with Bob Avery on a variety of issues, most of them were caused by the operator (me). I've received nothing but great service from him and others at Avery.
If I was local to him, I would be in constant trouble with my wife. I'd probably be buying something new every couple weeks.
Buying tools has turned out to be a very personal process. What I may consider good, you may not. Additionaly, features that I consider critical, you may not rank as highly. In otherwords, I don't think there is a one size fits all answer. If you're interested in what tools I purchased from the various vendors, please send me an email.
