If you have four build possibilities that you're putting up for a vote, then I'd argue most likely you shouldn't be doing any of them. It probably means you're not on to something particularly interesting, you don't have a particular interest in any specific one of them, and I'd consequentially argue your time is too value to treat that way.
Better to spend a little more time and find something you really, really, really want to do; or something that you've thought of that serves a pent-up need that isn't being well serviced (or similar angle).
Don't do something with this domain just to do it. That's a good way to lose six months, or years, of your life you'll never get back.
I don't say this to imply that you shouldn't do anything, but rather, that being selective about serious time investments is important.
