Actually, I have found that you can get both or either in some cases. Some loaders will fit different tractors and you can go for a heavier duty loader such as those made by Quicke. I believe Woods also makes loaders and we had a Westendorf loader on our Case. If I had not been so rushed, I would have seriously considered going heavier duty with my last tractor/loader.
Of course you may very well be right about the poster's comment on FEL/bucket, just thought I would mention the options available.
