Generally speaking, a higher-end establishment will be more likely to provide a more attractive selection of girls, probably their selection process is more critical and the facilities will be better maintained,
It's not likely that as a first time gaijin visitor you will get to pick from all the girls. Even Japanese people sometime need to return to an establishment a couple of times (or be very friendly) to "unlock" all the girls.
For me, visiting Dolce, I got a selection of 5 out of available 12 on shift. Some got a selection of 2-3 girls. However, visiting Club Amour in Osaka, I got to choose between all available girls upon first visit.
You may expect better service, but since it's your first experience, it all depends on your expectations too. Think about it like losing your virginity (generalizing): it's likely that your first experience was awkward, perhaps with a girl that wasn't a beauty queen, and you didn't quite know what to do or when to put your hand at that moment. Even if one of you was more experienced, it wasn't always helping the other feel at ease. Now add language barrier on that, et voila!
