To demand a raise of that size from your current employer would likely sour your work environment there. Put yourself in the current employer's shoes: it is either an admission from the company that you're severely underpaid or carries the expectation that you'll be more productive to earn that raise. Yes they didn't have to try to recruit and train to replace you, but a raise of that size quickly overcomes the cost of a new hire (if they're brought on at 1x or less of your current salary). If the money is important enough to you that you want it, then I think you'd be best off getting it from the poaching company. They'll be glad to have you - it's why they made the offer - and they are bidding for your current/potential productivity level.
