When you familiar to "to the strongest" then "for king and Parliament" is a good decision.
To make your decision harder I threw in the set from Bicorne Miniatures "The kingdom is ours". It is, in difference to Pikement's lament, made for P&S-Era and ist fast.
1644 has a great campaign system, and the rules have some nice ideas (the way cavalry melee progressively pulls in more and more ranks), but the combat system is very deterministic; you know that you will cause 2 casualties with a 50% chance of causing 3; that sort of thing.
Pike and shotte is a great set of rules and delivers fast play big battle games...it's our game of choice for this period. The supplement is also worth having
