I think that whirlwinds are very underestimated. Some people deliberately play horde armies to negate those lists designed for marines. A whirlwind is cheap and rather more killy on any kind of infantry than it looks. It also launches a giant pie plate to catch more enemies.
Although I have recently had success combining it with a tank popping unit. The transport gets taken out first then the troops are clustered for that pie plate. This could work with vindis but the I prefer whirlwind since it has longer range and can fire indirectly so there is less chance of retaliation on your vehicle.
