Just closing the loop here, I ended up ordering the card and will close the other (my current one) when it comes as I have accrued 270k points in about 2 years on the corporate card, averaging about $15k / month on that card. So 50k points would be a lot to add to a personal card, especially since I'll be averaging far less than $15k / month on that card.
Thank you for all your help, everyone.
