Ford F350 7.3L crew cab standard bed owner here. Would do the same over again. I drove similar Rams as well. I like the seating position in the Fords better - front visibility seams better and the dash/shoulder line does not seem as high as the Rams. Also, the Ford has a flat cab floor which is nice for carrying belongings in the cab with the rear seats up whereas the Ram trucks have a center hump and most have a molded compartment under the rear seat. The rear seat & leg room is also greater in the Fords. I have had two 7.3 gas trucks and enjoy the motor's performance. My 10-speeds have been a bit finnicky, but haven't failed. the 6.2L is also a sound choice as its been in production for a long time and is proven.
One thought on 3/4 vs 1-ton: Depending on where you live, there could be quite a difference in registration costs based on the stickered GVWR, i.e. CA really ups the cost for anything with greater than 10k GVWR. If that's not the case, the 1-ton would be my choice for the extra capacity on the sticker (most of the mechanicals are identical on an F-250 vs. F-350).
