In my opinion, it's not worth hunting down spicy instant ramen; it's just not usually that good flavor-wise. Find a type of ramen you like and add your own hot sauce/diced peppers/whatever.
My favorite is
Raoh. I don't know how common it is in other places, but if you can find or order it, definitely try it; best instant noodles I've found. I think the tan tan and tonkotsu flavors lend themselves best to this, but it's entirely up to taste, and whether you want to bother with the packets or not (though Raoh also does a particularly good job on that part).
To actually contribute...
A friend mentioned this to me, and I figured I had to at least try it; pretty bold claim, "Michelin Guide" instant ramen. Plus it's 7/11 brand, and I love the convenience store food here.
It was... just OK. Not as good as Raoh, but the veggies and the tiny bit of pork were a nice addition. I forgot to even check the price, though, so it's hard to say what kind of deal it was.
As far as the last restaurant ramen I had, this is from my last "holy crap that was a lot of booze" trip to a fast food ramen shop with the wife:
Yes, I was drunk, but even then I'm pretty sure it was better than passable. Quail eggs instead of chicken, so that felt kind of like skimping, but oh well.
There's a spicy tsukemen (dipping noodle) place I've been to a few times that's absolutely brilliant; I'd love to go back and get pictures for you guys, but it's only got three seats, and there's always a line around the corner (even and perhaps especially between 3 and 5 AM, but also during the lunch hour). It's an investment.
So here's a consolation prize from my favorite local place. Note the garlic press and bowls of garlic they leave out; definitely part of the reason I love this one.
