If space is a concern, then 1/43 is the way to go. In addition, I believe 1/43 are more popular in Europe, which is why Minichamps made so many 1/43 models already.
Since the scale is much smaller, you don't see as much details, but there are several really good models out there with engine details (Kyosho's Miura SVR, Lancia rally car, all new BMWs from Minichamps). The Handbuilts also have really good details, but can get very expensive.
Recently, Autoart also used carpet on their recent E-type cabrio release, which is a huge suprise. Also, if you like variations on a specific model, you can collect them much easier than 1/18 becasue it's a little cheaper and much smaller.
As for them being toys, I guess that's just a personal perception, I see 1/18 models from Maisto and some other brands as full time toy car as well, but that's just becasue I grew up playing them.
