As far as comfort goes...it is undecided...!!!
I, myself never had any problem with the seating position, but many complain about it (since you cannot stand up very easily)..
The controls are all "IN HAND" and logical..
Most WD's and "45's" had LOADED rear tires because MORE Traction was what either one of them needed...ours even had (still do) the front tires Loaded also, to help hold the front down...(we worked them pretty Hard)..Most WD's ended up with "13x28" (now 14.9x28") rear tires..same as what came on the WD-45..
They made an excellent "Baler Tractor", etc, as you could slip the hand clutch and stop or slow for big Hay Slugs, etc..
