It depends. Unless you have a lot of nanos to burn, base your decision on the common units. At level 70, it's offering the Mega Tank and Elemental Trooper (which are low-level (50 and 56) but still useful) and Railgun Tank (which was always useless because of its crushing vulnerability and lack of anti-air). At level 41, it's offering the Veteran (BUY BUY BUY, you can't normally get it until 47) and the Basilisk (meh).
