Welcome aboard ! 1/16th is a great scale, lots of parts available, decent size and won't take your back out lifting them. I think Heng Long is the best of the cheapy tanks, WSN and Matorro have ultra cheap electronics and/or drive train. If you like building quality models the Tamiya 1/16 tanks are awesome but where as a HL can be bought on a whim the Tam purchase requires more thought and financial jockeying. I have built 2 Tam's so far and want a third but I have to choose carefully because it will be a year or more before my next one.
