Rather than "settle" for either, I will be eagerly anticipating the release of the iPad Mini 2, which will hopefully be the best of both worlds. If anybody else is on the fence about this, I would suggest waiting also. Now let's just hope those March release date rumors are true!
And while you are waiting, those of us who have "settled" for either a mini or the 4 will be enjoying our tablets.
Seriously, waiting might be the right decision for you, but I think not waiting is an equally valid decision. I wouldn't be suggesting either option for other people, everyone have to make the decision that is right for them.
