I'm stating this from my experience w/ my 82 CJ5, but by adding fuel injection my MPG went up.
If this were my daily driver I believe going w/ the added fuel benifit of injection would be the best choice.
I do not know if the added MPG would happen w/ a 22 series injected vs carbed??

Toyota carbs are pretty good at mpgs, the 22REs mpgs won't be that much better. EFI probably has a little better capability to adjust for altitude, tire size etc, but don't quote me on that.
Pre '85 22Rs had double row timing chains which are inherantly stronger, BUT changing the timing chain every 100K should avoid any failures in the first place.

ah comon DC, he's a relatively nu-B 
lol, there's a lot of people out there that still run carbed daily drivers, and they do just fine, but they require little tune ups every once in a while, and you might could get a little better MPG with an EFI'ed 22re, but nothing too crazy
I've known guys to take the injected system off of their 22re (and even other motors that aren't Toys, like early TBI Chevy's) and put on a carbed setup, just cause most say it's "more reliable with less electronic parts, and is easier to maintain". Either has it's pros and cons, just like anything else, but they're both equaly as reliable as the other

Like everyone said, there are pros and cons. They have all been listed in this thread in previous posts.
One thing I will say in regards to the EFI vs. Carb is that you can get more performance out of a carb set up. EFI's are very hard to tune unless you want to get into major ECU tuning.
You probably wont be drag racing lol so either is fine. I like my EFI for when I go in high altitudes and it automatically adjusts air fuel ratio and keeps up efficiency.

IMO EFI may be more reliable on because EFI wires don't wear out and leak like vacuum lines.

My experience is that all goes to heck when you pull a vacuum line off a carb to simulate a hose failure. Not so much with the 22RE, who knows what those spaghetti hoses do, but its not that important. EFI seems to be able to compensate.
For reliability, I'd rather have the electronic sensors. They not complicated, they're durable and they're easy to diagnose and fix usually, but I never had a sensor go on my truck, my 22R was harder to diagnose and fix, in my experience.
Remember, these aren't simple carbs, by the late 80's carbs were getting very complicated to try to stay within emission specs that they're a nightmare to work on. Think about it, which is more complicated, a mechanical system using pressure gradients to account for elevation, throttle position, temperature, OR a couple stupidly simple electrical gauges with a couple moving parts telling a computer about as sophisticated as a digital watch how many times a second to pulse and let fuel out the injectors. EFI is more complicated than the carb on a Ford Model T, but less complicated than an emissions-compliant carb from the late 80s'.
