I use Kimber 8TC (long 25' runs) and I like it, provided you can find it for a reasonable price. I cant recall what I paid for mine (used), but it was sub $5/ft. I've also used 4TC and liked it, but wanted heavier guage. The sleeper, though hard to find, is the Kimber 4/8VS wire... same stuff, just not teflon insulated.
I much prefer spades to either bare wire or bananas as well. Bare wire could lead to shorts over time if you're not careful.
I've never used the Eichmanns, but they seem somewhat fragile.
