Tell me why I should or should not switch to fuel injection!!!!!!!!!!!!!!

I have a dual quad FiTech on a tunnel ram. Had 390s, then 600s, then a single 750.
I've driven it everywhere, every type of weather, short or long distance, with all combos. I don't miss carbs at all. Tuning is simple, from the driver's seat, and I can keep tabs on many parameters easily and accurately.
It made me rethink other items, tank, alternator, wiring, fuse box, fan, linkage, etc. I learned a great deal and made many positive changes.
Once I got the efi it was a few simple things I noticed that made me think why aren't carbs better by now? The throttle bodies have the return spring built into them, and for me that eliminated multiple springs and brackets. And right out of the box, why do I have to remove the carb to adjust the rear fast idle?

I had to learn myself on carbs, then on efi, not a big deal. I had an efi turbo car for decades and knew less about that than I know now. I also never worried about a sensor going bad on that car when driving it, and I don't now.
I too was nervous based on all the info and threads of issues people were having, but soon realized most stem from confusion or need for information/education.

The reality is you will never find threads that go on for pages from people who are happy with no issues, on any topic. It's similar to a call center that receives nothing but compliments and thank you's.
