Buying in LLC vs Personal Name

[Brit Hale]

In regards to purchasing long term hold rentals:

In my market, it seems that an investor purchasing a rental can get a 30 year fixed mortgage in the range of 4.0%-4.5% with 25% down when purchasing in their personal name. 

Purchasing through an LLC requires less down (15%-20%), but the rate is 6.0%-6.5% and a 3 or 5 year commercial note.

I'd like opinions here as the personal name purchase seems more attractive to me, partly because I personally guarantee everything in the LLC anyway, so I don't believe that I'm really offered more protection. Legal answers are welcome, but practical answers and personal experiences are preferred.

Thanks!
