Yup, the DC-3 is indeed a big ***** cat.
Got a few hours in the B-18, small, twitchy, noisy and cramped compared to the -3, but some guys love the -18.
Also flew C-180s, C-185s and C-188s hauling fish in Alaska, fancy footwork and crosswinds, but good fun. Back then. Probably too chicken to go back and do it now

As for OP: Go fly the DC-3 if you have a chance. Looks good on your resume if some old Chief Pilot looks at it, and you just may learn something about flying while you are having fun.
