Hard question... I have the following TOBS creams:
St James
Rose
Mr Taylor
Almond
Avocado.
If I had to pick one, it would be the St James hands down. Lovely top notch cream with an outstanding scent. The Rose and Almond would be a close second.
I would hate to narrow it down to only one....it so much fun to rotate through the whole line. Throw a couple T&H scents into the mix, and you've reached shaving nirvana.
