Hi there, welcome to the forum.
Of the cars you've looked at there the only serious 'race' car is the losi.
It's a micro class car, and the micro scene is a growing and constantly improving class of racing...and that car will pretty much work for you straight out the box!
But...if your looking to start club racing...and before you spend a penny...find your nearest club(s), go along, have a chat with the guys there, check what classes they run and what cars are popular, what the trackside shop supports (if there is one!) and go from there. Support will be a big part of the hobby if your fairly serious about racing at a club.
Your budget is going to limit your options to begin with...so you may want to explore 2nd hand cars/kit as well.
If your just interested in bashing around on your own...then that's quite different! Any of those cars would be fine I would guess?!?! But I would check our spares availability...you will break stuff...some more than others...but we all do!!!
Hope that helps!
