I don't have a TKX but do have a Richmond Street 5 speed.
The Richmond is a close ratio with 3.26 first gear and 1:1 5th gear.
I would prefer a wide ratio. You don't need to shift as often and it takes better advantage of the Nailhead torque.
The wide ratio TKX 3.27 first gear would work better with a 2.78 to 3.08 rear.
The close ratio 2.87 first gear would like a 3.23 or up.
This is because of the resulting 'starting line gear ratio'.... it's just the rear ratio multiplied by the first gear, such as:
TKX wide with 3.27 first:2.78 rear => 9.09 starting line gear ratio
3.23 rear => 10.56 starting line gear ratio
TKX close with 2.87 first: 3.23 rear => 9.27 starting line gear ratio
3.55 rear => 10.19 starting line gear ratio
A 'starting line gear ratio' of 9-ish or below means it'll take a little more clutch slipping to get the car going. A ratio over 11 makes first gear almost unnecessary for street use.... you could start out in 2nd gear.
You can also compute the highway rpm with different gear/tire sizes with a calculator:
