depends on what you want to keep. research what livestock you want... fish, corals, other invertebrates... and then figure out if that is the tank that will keep that livestock. if not, it isn't the right tank for you, if it can keep what you want, then go for it.
the best teacher is experience. there is more than one way to skin a cat in this hobby and the only way you will truly know if you like it or not is to try it out.
what many people mistakingly do is buy the tank and equipment first before they know what they want to keep... and then end up having to upgrade everything... lighting, pumps, powerheads, filtration, skimmer, etc. etc. don't be one of those people. take your time to research, ask as many questions about livestock as you can and then pull the trigger on a purchase.
welcome to the forums and I hope you enjoy your day.
