Might I ask why "hotter" is what you are going for? Unless you are in a situation where your PA is out of headroom or your sound guy decides that all the sliders need to be in a nice straight line across the board at 6, isn't "heat" controllable? Maybe I'm missing something.
I'm a big fan of Audix. For vocal applications the OM3 and OM5 could be considered their take on the SM58 and Beta58 respectively. They both sound great and don't have that SM58 muddiness, which I find works well for my voice. The tight hypercardioid pattern is a bonus if you have a fairly heavily mic'ed stage as you can get away with high gain without feedback issues. Your mic technique needs to be more of the "eat it" variety than the 2 feet away off to the side variety as a result, which may or may not take some adjusting depending on how you sing. Price wise the last time I checked they were the same as the SM58 and Beta58.
