EdC is not the same as an AS ... if you're just going for fragrance, sure, splash it on. But if you want it for skin conditioning and easing of razor burn, it will probably not function the way you want it to.
I'm a sucker for anything Lavender, so I've been trying the Ach Brito, the Agua Lavanda by Puig and TOBs Lavender water. None of these are technically aftershaves, so my post shave routine goes: Thayer's WH - Splash of either of above - finish off with some RazoRock King Louis aftershave wax, which compliments any of the above, and end up with a nice lavender blast! (for a short while at least).
Also to compare the above three products i think I like the TOBs the best, because it has the most natural, EO, dry, herbal grassy lavender scent. It's very fleeting though. The two Lavandas are more cologne-like with more staying power, and are quite similar, I'm still trying to decide which one I like better.
