Alchemical Golem vs Beam Golem

[DigitalBlizzNX]

I've been playing a Summoner for awhile now and been getting into it (Love this style of playing) so I was curious which of the two golems I should focus on since I don't think you can have one of each maxed at the same time. Thanks in advance for input.

Yes, you can. But, Alchemical imo. He's tougher earlier and you can always use another tank/AoE.
