I went with the 6 speed manual and I know that the heaviness or lightness of a clutch depends on who's working it, and what other clutches they have used were like, but personally I was surprised by the lightness and user-friendliness of the stock clutch in my t. I wouldn't worry about it when making the decision, I guess it's more what sort of driving experience your after. I find that driving a manual is much more involving and really gives you a feeling of being one with the car, or being in total control, but that's me. I guess either way you'll be happy, as we all know these cars put smiles on dials no matter what the transmission.
