If you really are only going to do a handful of dives once or twice a year, you won't have enough experience in your own equipment to make it significantly better than rental from that standpoint.
If the majority of your destinations would be high-volume dive sites like Cozumel, Bonaire, Hawaii and the like, I think you'd be fine renting. As Leejnd recently discovered, dive ops in more remote places may have more questionable equipment and procedures.
Dive gear takes up a significant portion of one's luggage, especially in today's bag-restricted world.
I own my own gear and take it ANYWHERE I am going to dive, even if the diving is not the primary focus of the trip. But I log somewhere between 150 and 200 dives a year, and my own equipment is like a second skin -- AND I go weird places and dive where the infrastructure isn't impressive. If none of those conditions applies to you, you are better off renting, I think. The one thing you might consider acquiring is your own exposure protection, because wetsuits quite simply don't work if they don't fit.
