The only reason that I could see to use the Taylor was it could save a bit of rifle weight by going with a smaller action, in my case the CZ 550 vs. the CZ 550 Magnum.

Yeah, the internet can be a source of all kinds of bad info, such as in the case of the 416 Rem. Mag. Have used it a lot in Africa and nary a problem. It feeds slick and has enough power for 99% of DG situations. And like you say, almost every PH and their dog is using one.

The other nice thing about the CZ 416 RM conversion is that it holds 5 down and 1 up. It weighs 8.9 lbs.

I had some drop floorplates made for my 416 Taylor so it holds 4 down. Almost as good as 5!
