I have and do on occaision MIG, oxy-fuel (mostly for cutting) plasma-cutting, and a tiny bit of TIG... MIG does NOT make a lot of splatter if you are doing it right (adjust settings for current and wire-speed, and keep the distance right), and is pretty easy. TIG is trickier because most TIG machines use a foot pedal which is a bit of a challenge for us
However there are some torch setups that allow a finger or thumb control instead. Some of the fancier machines also have setups that supposedly allow a 'scratch-start' like stick, and then 'auto-control' with some metals.
Leather aprons are good. I will also sometimes take a pair of leather chaps from my riding days and zip the legs together to make a cover to drape over my legs and feet. AVOID SYNTHETICS, wear wool or cotton clothes! It's worth noting that a lot of welding jackets and aprons are actually thick cotton w/ a flame resistant coating.... However to me the most important thing is to set up the work to avoid getting your feet in the way of splatter...
To me it is not something to be afraid of, just use caution....
