My first tractor, a Gravely, was too small after I got used to what I wanted to do. Bought a 4010, smallest with full Cat 1 hitch, at the time. It's a perfect fit for what I need to do on 8.5 acres and across trails of another 100 acres or so.
Neighbor asked me about digging up some stumps. Advised him that a FEL is not good for that: needs to rent a back hoe. Exactly what I'll do if I need one. Same for a trench digger, etc. A tractor you use all the time doesn't have to do everything, like my Tacoma won't do all the truck things one needs to do. You can rent stuff for the infrequent things. No sense wasting the planets limited fuel resources in lugging a big tractor or big truck around, just because you need to RARELY need some big power.
I'm against bigger, badder stuff. Most of you probably buy them just to brag. Think about the earth and its resources. Smaller is better, unless it just won't do your everyday work.
