I say leave it in. It could add interest to your quilt to have both.

Think of it as a quilting 'sampler'. Using both hand and machine quilting would be just like using different blocks. Maybe you could put few a few ties somewhere to make the quilting sampler concept more complete. And then convince yourself that you planned to do it this way. No one needs to know anything else!

I like renee765's idea to have different types of quilting if it works with your piece design. Or, let it rest for a bit and then decide - you may decide to finish hand quilting it, or come up with something different altogether without ripping out all your hard work hand-quilting.

I second this. It was your first hand quilting, big stitches included, I think you should not take it out. Also maybe you want to have a hoop lay around the house and let the kids finnish or yourself, over time, while using the quilt. That is if you want to finnish the hand quilt part too. Kind of a usuable practice bat for hand quilting.

I think you won't be happy with it the way it is. In that case you are better off unstitching it and starting over.
