If you can store it at ground level where you can move it with a hand truck, wheel barrow handles, or a dolly of some sort, a 14" will be easier to use than the telescope you have.
If you can't, then that is a different story. The base on these mass produced units way in at a hefty 75# to 85# and I can tell you that the shape makes them awkward to pick up even though they have handles. The ground board forces you to lean quite far over because there is no way to lift with only your legs. If you think you are prone to back issues do to age or other factors, this should be a serious consideration. The OTA will also be heft and not super manageable.
If you go for a new super-fast premium reflector, at this point in the expenditure curve, you might want to start considering an image intensifier and a 10" Dob with Go2. The 10" is far more manageable.
Dismiss the remark about crummy optics. I do not think that is the case at all, though the optical quality would be variable and you should have no reasonable expectation that they would be excellent, though my own 12" Go2 dob did have quite good optics.
Anyway, even with a cheap 10" dob and an image intensifier, you will see things that you would not be able to see in a 14" or even 16" dob.
Commercial 14" though is going to be heavy. If you don't have a roll-out storage location, it is a lot to manage.
