First off let me say I'm not a BMX expert but I have had a few bikes for my kids.
The ones you linked are obviously budget items but probably none the worse for that. Budget bikes tend to skimp on things like no rustless spokes plus other things which I'll come on to. Aluminium frame on the first so should be quite light but the Legion has a steel frame which will be noticeably heavier, weight is not quoted for the Legion. One thing they don't have is a brake cable detangler on the headset which will be a disadvantage when doing freestyle. Here's a pic;

So you won't be able to spin the bars. Don't know if this is important to you. The Legion has the more powerful scissors type brake while the other has a V brake which is still effective.
The Legion will have much lower gear than the Title judging by its small front chain wheel. I don't know the importance of that or what is the best option so you'll have to check that out.
