I have done both. I think the CIS rebuild ran me about 2k, that included new injectors, sleeves, new hoses, new plugs, cap, rotor, and wires as well as a dizzy rebuild.
I recently went to carbs, I don't know exactly, but I think I'm up to about 6k for the conversion. Probably more.
The difference is night and day for my 2.7. in terms of excitement, thrill and just outright fun.

CIS wasn't perfect, it had tuning issues all the time. I spent 2k at shops over the years dialing it and having it tuned as well as countless hours tuning it on my own. Still it was more reliable from a "get in, turn the key and don't worry" standpoint.
The reason for that is that the carb install is DIY and all new to me, so my confidence that it wont burst into flames isn't as high as It should be.
I also think I need to do more, I have my CIS pump regulated, but I think it's causing issues because the pressure is still too high with the regulator wide open. So I might swap to a low PSI pump. Which means changing some lines etc, probably another $200 job.
I went with vintage webers, and it was a ton of work to bring them around. Even now I'm having a leak, I think it's boiling on the left side after it sits, so I have more trouble shooting to do. The slightest leak and it stinks up the whole garage, but the second I drive it, all is forgotten.
It's a weekend thrill toy for most of us and even with my worn out 2.7 (160k miles) it is really really fun to drive with the carbs.
It also looks SOOOOOO much better than the CIS.
