EFI -VS- TBI which one-good-best-better?

...well as it goes I went with Edlebrock EFI. It didn't happen fast like I wanted it to but Tech Support is quite the education. First problem was they're tablet was cracked corner to corner. I actually thought if the tablet wasn't on it wouldn't start-wrong. I wasn't ready for it to and it did.
The birth defect mine has is that trying to set the initial timing at 12°. It always wants to do 8°. I ended up using a kinda homemade piston stop for it, backing down and re-checking until I finally got it there (going back and checking it again pretty quick) but have this idea it's still off a degree or so...like just enough to make it run a little rough.
I had a hard time before I took the wet fouled plugs out also, took right off after that. It draws a lot of electricity. About a whole volt when it fires. I was going to replace the alternator/voltage regulator next summer, did it now just to make sure I wasn't missing out on any thing a new one could do for me, and now replacing wires as needed. Most of it is pretty much in great shape, there has been somebody under the dash before me, and I am fixing their stuff. Probably see a full wire harness replacement in a couple years. I solder when I crimp, its the only way they last on some of the bigger and heavier load wires. And the ignition system is totally isolated from the rest of the system, kinda neat for finding things that need fixed!
I don't think I would of liked the TBI type. Saw one right before I ordered this one. Didn't impress me any, plus it was on a mousestang 4 point something, I don't know much about those cars any way but it sure seemed like it was just regular non spectacular barely burnt them off and sputtered on down the road...was not impressed.
All in all it was an easy install, I got a little more smarts, affordable, and it seems like I am getting better mileage, it runs cooler, and weird thing, on the highway it gets to that 85 mark at about 1700 RPM. That used to be about 2600 RPM. Oh, 85, I don't think the speedo is right. I am replacing the cable and putting the clip that holds it tight to the back of the gauge on after I get one-friend says he has a few dozen to choose from. Pulled the cable up about 6 inches and it was feeling fat and fluffy in spot, probably causing speedo things to be wrong because it flexes funny if you twist on it-just needs replacing.
Thank you guys for the info, it did really make it easier. After 3 months of this and that I'd help someone install one and feel pretty confident about it, if your even ballpark with settings it still starts and learns while it is running!!!. Never like that with carburetors, always had a prayer going with those for some reason-even when they were running right.
Again, Thank you for the info, helped huge with the choice...
