Was switching to IFS worth it?

[la hi]

I am now driving the truck every day and the bouncing, rattle, and jolts are getting to me.

I have stock front end, leaf springs and coils over the shocks, a good sway bar to support the 454ci and a stock rear end with sway bar.

My question to all of you that converted to IFS--was it worth it?
Question 2 did you weld from an old car, or did you get a bolt in system?

thanks
