The SV650. It’s a better bike overall.
BUT there are plenty of non-monetary reasons to consider as well (most of which have been summed up nicely here), as well as more removed-from-the-immediate-purchase-price ones of insurance cost, condition of the bike, need for repairs, etc.
Whatever you choose, don’t stress out about it too much. Despite what you may think now, this is not going to be the last motorcycle you purchase.
