Some taildraggers (exceptional) exhibit a strong preference for one type of landing or the other. For example a DC3 is normally wheeled on. I understand the same is true for the T6. Other aeroplanes don't tend to like being wheeled on such as Pitts S1, for example.
But in most cases, in my experience, both are possible. I agree with GtE on this - the option to use a wheeler landing made my life a whole lot easier when landing in 15G28KT conditions with additional turbulence from trees. Out of interest, I added around 10mph to my normal approach speed from 60mph to 70mph. This smoothed out some of the lumps, making the sink bits less painful and giving me just that little bit extra control authority. I was still stopped, no brakes, in a couple of hundred metres from the runway threshold. Worked for me, but then I know that aeroplane reasonably well, and had practiced lots of wheelers. Incidentally the type doesn't wheel as nicely as some others, and is much happier when 3pointed. But in this case the wheeler was hands down the best way to do things.
Fly to the conditions. Know your aeroplane and how it responds in slow flight. Then it'll tell you if you're getting too slow, and it'll tell you when you have things about right. Just IMHO.
