Need to replace drivetrain and trying to figure out what set to upgrade to

Hi everyone,

I have a 2008 Trek Madone 6.5 that I bought used a couple months ago and I am having trouble getting everything to shift correctly consistently and my bike mechanic said I just need to replace my drivetrain because things are just getting worn out. Ill list out everything the bike has currently below, but Im trying to decide if I should buy a completely new Shimano 11 speed 105 R7000 groupset or spend a little more and get the new Ultegras, or just replace chain rings, cassette, front derailleur, and chain with Ultegra 6700 (which I believe is a 10 speed, so I wouldnt have to do anything with the wheel hub). Will I be able to tell a noticeble difference with a newer 105 11 speed, vs older mix and match 10 speed, or is not worth the extra money??

The bike has a bunch of mismatched things but I will do my best to list everything
Shift Levers - Dura Ace
Front and Rear Derailleurs - Ultegra 6700
Brakes - Dura Ace Rim Brakes
Rear Cassette - 10 speed Ultegra 12-30 (6700 if I had to guess but not positive)
Crank Rings - 50/34 Sram powerglide
Crank Arms - 175 mm Bontrager carbon fiber

I have never done this before, so any other advice would be appreciated!
