Good one, same pieces, but it's double check!
I think my checkmate is more beautiful because the pieces cooperate to the maximum, not taking any squares away twice. Always great to see mating patterns, the second one was more of an opening disaster to my eyes, mine was a swindle 
I was playing teams and had to take a 30 minute break to soak in the beauty of the following checkmate! After blundering a nice countersacrifice in the opening we had been down a queen the whole game, but it was not so clear since we had a bind on the blue king. My teammate was mated in two moves, but I had a counterattack against both players (backrank and matethreat). In fact in the final position before blundering mate my team would be up two pieces. The final move was Na7#:
