Tent will definately be better. Their good. No mucking around, youll have intake/vent ports rails to hang lights etc, they reflect light, you can run it pretty well sealed and dose co2 later if you wanted. But I found this way increases heat and humidity alot in tents. But alot more options and also light leak proof if you get a good one!! If the tent is on the smaller side, you can always use it as a cloning/veg tent later on and get a bigger one for flowering if you wanted to go perpetual at a later date???
