There is more of a "wow" factor as they come onto boost.
To anyone that hasn't experienced turbos cars much, the one that feels the fastest is the one that has the bigger transition onto boost. Eg, if it makes 100kw at 2500rpm then 350kw at 3500rpm that's a Fkn huge shove in the back over 1000rpm spread. That will impress your mates and will feel quick. Plus driving a car like that has a certain appeal, it's fun to feel the transition and get pinned to the seat.
Edit; also when you get used to the power of them at 1bar or whatever, you can turn them up to about 26psi and if the rest of the car is up to scratch you'll be over 400kw.
