I might just add my own experience to all this, which is that the 2L TS (CF2) in my Spider doesn't feel the same as the 2L TS (CF3) in my 156.
In my 156 the engine pulls willingly and smoothly at any speed. It doesn't feel very powerful at open-road speeds but it is effortless at low speeds, smooth and quite nippy. Seems to maintain speed easily up hills and is a quiet and economical cruiser with a lovely burble at 3000rpm (has to work a little hard for overtaking, doesn't feel like much reserve of power).
In my Spider the engine is smooth, but feels like it bogs down trying to move the car away. Any attempt at a wheelspin start and the engine practically stalls. Then flat out in second, performance is sufficient but seems to ebb and flow as the revs increase past 3000, tailing off and coming back twice before 6000. Previous owner had the airflow meter replaced with a new genuine part to try and correct this. Overtaking reminds me of my pristine low-mileage '88 X1/9, whose 1500 engine didn't really seem to enjoy the revs (more shrug them off) and with 85bhp also wasn't overwhelmed with its own power. The fact the power is sufficient is enough, but I did expect the power delivery to be smoother and I especially thought that it might be capable of spinning the wheels. Doesn't quite have the same burble as the 156 but has a pleasant growl instead.
On the basis of my 156 experience, I picked out a TS Spider and ignored the four V6 examples that were for sale (most Spiders for sale here are the V6). So I guess I can agree, with the benefit of hindsight, that the V6 is the better engine for the GTV and Spider (which are heavier than the 156). Unfortunately my Spider cost top money and it's unlikely I'll be able to sell it for that to make the changeover economic, so I'm stuck with the TS for now. One benefit is that I am getting 38-42mpg. It would be interesting to see if it's possible to upgrade it to CF3 spec (CF3 has 5bhp less than CF2 and presumably picks up torque at the bottom end as a result). I wonder what is different, since the cam locks used when changing the timing belt are the same.
