There is of course some additional overhead associated with the TCP protocol though, which is why it really depends on the reliability of your network and clients to determine which of the two protocols is ideal for your environment.
Certainly in the situation being described, where a client is dropping packets, TCP will likely be the better choice. (Though I'd also want to try to address the dropped packet problem as well if possible.)

UDP has no retry mechanism so if you loose any of the 22 packets involved
in a 32k transfer then you need to start again. A powerful server sending
to a weaker client is a good way to ensure that packets are lost. TCP has
mechanism to ensure that packets are not lost and hence works better when
the packet recipient is the weaker partner.
