leo's are pretty good about being handled so long as you know the golden rule of geckos's "Never hold them by the tail" Leo's are nice cause they can live a saller tank their entire life as a BD needs a larger tank as an adult. BD's are higher cost due to the fact that they love to eat the first 6 months will cost you the most money then it tapers off since you wont be feeding them cric's daily. I own Bd's have taken care of leo's while friends went on trips out of the 2 I like BDs for the socialness and Leo cause they have some Kick butt colors.
BD's as a starting Lizzy are a good pick i think. They are friendly require little taming to handle, care needs are easy hot and dry. I use repticarpet change it out daily rinse and repeat. Provide a water dish (so they can have fun splashing water all over the tank) a full bowl of greens daily even if its not eating them, mist in the morning cricks in evening but make sure the light is on for atleast 2 hours after the meal and all cricks are out of the tank before ligths out (BD's are very heavy sleepers and crics will chew on them, Never seen this happen but wouldnt want it either).
All in all pick the lizzy that you like best research its care needs and then decide "can I take care of this guy"
