I really like Meg's products . . . here's my stash:
DC1 paint cleaner: a very under-rated paint cleaner. For $5 OTC, it works wonders on minor swirls, especially when machine-applied.
DC2 polish: also under-rated
#26 wax: smells great, durability not bad, not difficult to apply, looks amazing
GC wax: durability not the greatest, looks great, super e-z to apply
Nxt glass cleaner: this is the best glass cleaner I've tried
Soft Wash auto gel: it works.
Endurance tire gel: this stuff is also amazing . . . lasts a super super long time. Smells like grape kool aid, which is fun.
GC instant wheel cleaner: does the job, but my wheels have sealant on them. Don't really like the smell.
multi-part wheel cleaner: I like this stuff better.
Scratch X: Should be part of everyone's arsenal. When you need it, you need it.
Nxt Tech Protect: I use this for black trim and wheel wells.
Final Inspection #34: A great all-around QD and clay lube.
GC leather cleaner/conditioner: Works as good as Lexol twins, and easier to apply (just 1 step), and smells much better
Quick Interior Detailer: Nice product.
Odor eliminator: When you need it, you need it.
Whew, I think that's it!

I do have an assortment of Meg's brushes and MF's. I do like the supreme shine MF's -- high quality, and you can get them for cheap if you wait for sales, etc., at the local OTC store. The brushes are nice as well.
Here's my stash of non-Meg's stuff:
Klasse SG: I like the durability, haven't been as impressed with the shine, though when topped with #26, it's wonderful.
Michelin Brake Dust Repellent: Seems to give a little more protection to the wheels beyond just Klasse alone.
Griot's paint clay: Will be replaced by another brand . . . just need to use it up!
Plexus: good stuff.
Raggtopp convertible cleaner/protectant products: good stuff.
I think that's about it!
