if you already have 20 top squad than use them for stamina refills after you get the best equipment doing this you get a free level and 5 skill points at least every 10 earned levels i saved all of my UN credits from level 50 to 200 150 credits and i was 230 in a matter of 6 hrs if you don't have the 20 top squad than i recommend getting the strikers or defenders i honestly see no reason to get them if you have 20 top but alot of people do it does give you a small boost in attack and is worth it if you have many Credits to spend for the small 2% boost i'd rather level again and get a permanent boost
most of all its gotta be what would help you the most
