Those are my two favorites of all time.
Yuma (my avatar) from World Trigger reminds me of Killua from HxH, so I’m watching that right now. 
Though they stopped creating it, because of negative reviews and stuff. I saw a lot of people complaining about the main character not being powerful, but he’s more of a strategist, than an actual fighter, even though he participates in the fighting. Which in my opinion is way better than in most shounen anime, because it is very strategic. Fights and preparation for fights are explained in-depth, unlike anime like Fairy Tail, where fights are pure power struggle and characters come up with new moves out of nowhere.
Characters have clear strengths and weaknesses in battles, which is what makes World Trigger exciting and fresh for me, same as HxH, but I think HxH is just much better overall.
I’m just getting sick of shounens like Naruto, Bleach, Fairy Tail, One Piece…where it’s the same thing over and over. Powerful guy shows up, then main character either loses and comes back with newfound power to wipe the floor with the bad guy, OR they win the fight in the end by summoning the mystical power of being pissed off.
Not the case in HxH, nor in World Trigger. Don’t get me wrong, though, I still enjoyed most of the major shounens, it’s just that I’ve grown out of them lately.
I can suggest a bunch of other anime, but I don’t think they’re really binge watching type, as they have one or two seasons. Oh, what the hell, I’ll suggest some anyway.
- Code Geass
- Anything from the Fate series
- One Outs
- Air Gear
- Darker than black
- Kaze no stigma
- Kaiji (Unique art style, might need to get used to it, but the anime is awesome)
- Aldnoah.Zero
- Trigun (Depending on your sense of humor, might be extremely funny. It killed me, Vash is so funny for me xD)
- No game no life
- Guilty crown
- Akira (movie)
- Speed Grapher
- Guyver, the bio-boosted armor
- Ao no exorcist
- Magi: The Labyrinth of Magic
I avoided suggesting FMA brotherhood, death note, attack on titan…etc since they’re crazy popular and most people watched those or at least know about them.
