I am totally neutral here and not slagging anyones comments, or playing ability.
I can totally understand what people are saying, I have only read a section of this thread as it is so god damn long... I agree with attitudes to people such as wooten, his solo stuff is too 'clowish' technically brilliant, but where does it fit into a set?!! But still, how many videos are there of people trying to emulate what he plays. Then you listen to something like 'The Vision' by him which is harmonically excellent. Also I have seen him live, and god cant he groove. Mark king again is another name that pops to my head... slap... all in E!!! But good in his way... people love his playing.
All of these people are unique in their own way. Jaco is a fantastic player, there might be people better than him now, and even in his time, but still his playing is special in its own way, and we have a lot to learn from these people.
As for 'session' players such as Jamerson... I have met and played with lots of 'session' musicians. I met a drummer, and I really cant remember his name... I will add it when I remember! He had played with sooo many people, and is really really busy... but he wasnt the most amazing drummer in the world... this narrows down to the 'who you know' situation, but no matter how good you are technically, its what you do with it, and how you apply yourself.
Also back to the situation of people saying 'Who is Jaco?' which I read earlier... one of my favorite players is Baron Browne (if thats how you spell it) he plays with Steve smith... fusion stuff, he is a killer groove player... BUT not many people have heard of him... fair enough thats what I LIKE... what my point here is that people have their favorites... im fed up of people saying at gigs "oh you play bass... isnt Flea the best bass player you have ever seen", yes I respect Flea and love alot of his playing, and one of my good bass playing mates plays alot of 'Flea like' stuff but thats who THEY think is good to them, so fair enough, its all down to taste... some people like Mark King, some Wootens 'Clown Playing' and the list goes on but its totally down to personal taste and preference. It doesnt matter if people have made it commercially, or have NEVER been heard of, im sure there are some incredible bass players out there who have never left there bedroom... Its all down to what people want to do and what people want to listen to!!!
Im sure I could list some bass players that I think are 'overrated', but if they are doing or have done something good on them!
At the end of the day, I know that I play, because I have a passion for my instrument and always strive to the best I can...
Let people listen to the music they want to listen to, and discuss it, after all this is BASSCHAT, where we discuss things, not rip people to shreds, if YOU dont personally like something, its not to say someone else doesnt!!
Damn im blabbing, really didnt get out what I wanted to say, but you may get the gist!!
