Some things never change: fit, not brand name, remains the primary criterion when choosing fins and a mask.
In the case of fins, make sure you try them on in the store and out in the water before you dive with them. Foot pockets are three-dimensional, so make sure they accommodate your feet comfortably in terms of length, width and height, with socks or booties on if you're not planning to wear them over bare feet in warmer waters. Too tight and they will cause cramp. Too loose and they will rub, generating blisters, or fall off. Only then take personal preferences into account. You say you have dived with rented equipment. Your experience will guide you when it comes to deciding what you like and what you don't like. Fins, like shoes, are very personal items of gear. Don't be bullied into purchasing the latest fashion, or a pair that doesn't suit your swimming stroke, just because other people think they're the best in the world. They will be the best in the world for other people, not necessarily for you. You have your own voyage of discovery to complete before you find the perfect fins for you. Fins are there to give you power, endurance and manoeuvrability, although no model will give you those benefits in equal proportion.
As for masks, check them out for fit in the store as well. Press the mask skirt against your face and breathe in through your nose to create a partial vacuum. Does the mask stay in place? If so, it's a good fit. If not, discard it immediately, however fancy the brand name is.
If you're getting a snorkel, a simple "J" type without valves is probably best, because there's less to go wrong.
Notice that I haven't recommended any brand names at all when giving you advice about basic gear selection. I hope that will help you focus on fit and performance rather than fashion.
