Does FT get better? I think so, but like as a whole I wouldn't say it's the greatest or even like Naruto lol. The best arc in the series, in my opinion at least, was probably the Tower of Heaven arc (ep. 33-40). The Edolas arc was also pretty decent and I liked some of the fights in the Tenrou Island arc.
However, the series fails to seriously develop any of the characters or advance the plot in a meaningful way aside from "fight for your friends." That's literally all the series is about period. It's fun, and there's good action, environments, etc., but it just feels like the series has lost so much of the appeal that it once had. It's not like Naruto where you get major character deaths, heavy character backstories, or serious character development (like with Naruto's encounter with Pain).
I dunno. For me I'm really torn because there's a lot to love and there's a lot to hate and get upset over. Just don't compare it to Naruto lol.
