Pot them on. All good,,tough plants. No they will not come on any quicker if planted out. On the contrary they will sulk in wet cold ground.
loosen any tight roots and water well. A greenhouse, cold frame or any contrived protection to keep them a little warmer and drier and away from the worst of the winter.
the herbaceous stuff, especially, will grow fast in a few weeks. A second potting on in early spring will produce far bigger plants to out out a month or so later.
I usually purchase lupins,,delphiniums, lychnis, etc. etc in 9cm pots in early Feb and by mid spring they have tripled, quadrupled in size.
