I tried this earlier in the year, bought an expensive safety razor, a cut-throat, fancy soap, badger brush, feather blades etc etc etc. Months later I use the cut-throat very occasionally because it gives the best shave but takes ages, the safety razor now and again because it's a pleasure but it's not as close and the razor burn on my neck & throat is fierce. Most of my wet shaving is with the Mach3 because it's close, thorough and quick with zero cuts and no razor burn.
There's a reason why cut-throats and safety razors fell into disuse.
When I told my dad I'd bought a safety razor he thought I'd gone mad.
