I'd go for the biggest - it looks like the fourth down. I wouldn't use a metal one (is the top one metal?) as it would heat up and honeysuckle like their roots to be cool.
Whichever one you use I'd line the insides with a good thick wad of newspaper before putting the compost in as even more insulation against the roots being heated by the walls of the pot if it gets too warm.
I'd also plant your honeysuckle plant straight into your big tub as if it was going into the ground, not into a smaller pot first.
As honeysuckle are woodland plants I'd use a mixture of John Innes No 3 loam based potting medium and I'd add some leafmould to that. I'd I'd also add some of the water retentive granules vhttps://www.rhs.org.uk/advice/profile?PID=692 to help ensure that the roots don't dry out as this will make the plant susceptible to powdery mildew.
I don't know 'Princess Kate' as it's fairly newly introduced, but it looks like a good one - if you choose that one (and I hope you do ) let us know how you get on
