is a TO3 case better?

[ppia600]

I prefer the to3p or to247 styles to the metal to3. Easier to mount, still have great heat dissipation and take up less space. Besides, the square type are more space efficient and you can squeeze more of them into a smaller space to achieve better overall heat dissipation.. kind of like using square subwoofers to utilize every square inch of space possible. Using a metal to3 type is kind of like driving a hummer to go off road when you can use a forerunner instead.
