I'd lean to the SOL 3, with the following modifications:

Bigger mirror.
Lighter and/or matches.

And I'd add a better compass to your overall gear. This is just a back up. Theoretically, you could probably get a slightly larger compass in here, but.. *shrugs*

That being said, I don't see the Top 10 as a survival kit with medical items, as I the SOL3. Instead, it is a FAK with some survival gear, but you still need to add signals and some more fire starting gear.

I like them both. I think both need to be tinkered with.
