I'm a big fan of the aggression of the '30s British 1912s (generally, ones with the "chain link" handles) and find the later British (into the '50s and often with the handle as shown by Tman10 tonight) to have smoothed that aggression without losing the efficiency. It's all in the minute detail, of course, but those minute details do seem to make a world of difference.
I concur with Billy over the US made razors. They're okay, but they're not the best. The earlier ones were of a much better quality and give a smoother shave, but I still prefer the '30s Brit over all of them.
I've seen Star mentioned ...
Star were also made in the US and GB. Generally, and this is a big generalisation, the ones marked "Made in USA" were made in the US (no, never!) and the ones marked "Safety Razor" were made in GB largely for the French market. Quality and shave is akin to the British 1912. If you want some real weirdness, there were some "Made in England" GEM 1912s. These are rare and I think were for the Australian market, a guess based on how few of them you see come up for sale and how often those are from Aus. It's a guess.
