First this is not going to be another which one should I buy thread. Instead I'm asking more about the components on these bikes. I know all about size, which one I think rides better and all the other common replies to these kinds of threads. But since I'm not familiar with MTB components I'm asking is there anything on any of these bikes that would make you rule it out?
You can tell (I think) from the list what type of riding I will be doing. Causal weekend old guy (50) not flying through the air (much) easy to moderate single track wooded dirt trails. I did a little bit of dirt riding last year with a friend and found it to be a blast so I want to do more of it this year to change it up from the road bike all the time.
Remember I'm not asking which would you buy. I'm asking which you wouldn't buy from a component level only. No emotions about brand like or dislike since I think I've picked out quality bikes for my budget and abilities. If I'm wrong on that point please point that out though.
I thank you for your time and input.
