Really it comes down to what works best for you. If you want the ability to update your mod, or just set Ti mode, etc. then that should be part of your decision. Most mods in that class all work about the same, and it really is personal preference on what feels better in your hand and what features are important to you.
As for owning 2 mods, I would suggest that everyone should own at least 2 mods, so that you have one as a backup. They don't have to be identical though, just capable of meeting your needs in case something goes wrong with your primary mod. Things happen, mods get dropped, wet, smashed, or just plain quit working. If you vape to keep from smoking, this could be catastrophic. I have had far too many mods fail, and thankfully I've been able to get through with a backup.
