paddle shifter
R154 is overkill for a stock 400, if you're not going to make more than 350whp, save the money and go W58. As for the original question, I would go 5spd and I think it maybe cheaper too. W58 and all the hardware are cheap, the adapter plates are the one that can get expensive, not too sure what the going price is at the moment though.

What I'm planning on doing is swapping the 6 speed A761e and use the IS350 ecu and true paddle shift steering wheel. I'm actually shocked that I still haven't even seen an IS350 or IS250 steering wheel in an SC300 or SC400. Those steering wheels are dope!
Just so you all know, instead of going the suprastick route, anyone who has a pre 97 SC400 can swap out the 4 speed a340 for the 5 speed a650 that was used in the 98-00 SC400 and piggyback an ecu from an auto is300 or gs400 to use the e-shift. For those of you who have JZ powerplants you can just use an a650 out of an is300 and, again, piggyback an is300 ecu. You'll need the entire ecu since the transmission ecu is built into the the main ecu. This route requires a lot of electrical and wiring know-how but in the long run will be much easier. Also, as mentioned before, a stand-alone trans ecu could be used also.

so, say the transmission is 300, quantum-auto kit's 1100, total is still roughly $2400 vs. $1200 for the suprastick. Again, the w58 doesn't include professional installation, if required.
Does the true manual justify double the price? I believe THAT is the true question.
Always make room to grow or you will hate yourself. Make a goal and 3 months down the road you are unhappy and getting smacked on by civics. R154 and you will always be good unless you loose your mind and go for 1K lol.
If it's anything like the oem e-shift, they arent that great, but are way better than nothing at all 
Well, I just wanted to let the OP know there are cheaper options to manual swaps. As for 5spd vs E-shift or paddle. Yes, to me it's worth it for SC400. Unless you swap to a real semi-auto trans, The e-shift system on lexus leaves a lot to be desired. Don't get me wrong, I still like it, but it's not great. At the end of the day it's still an automatic with the option to down shift 1 or maybe 2 gears down while driving, if the ECU allows it. It's better than auto, but nowhere near manual!
I never consider a w58 because of my goals
