Okay, so here is what I did with my light solutions. I bought 2 extra dust caps.
I first started with 55W HIDs. Relay kit to the battery and all. Super bright and it really lit up the road super well. Cheap Ebay kits that cost around 22 bucks with ballast and bulbs. Cheap ballasts and bulbs. I went through at least 4 of them. Every time I did a road trip to Florida and back, at least one one HID died. Once it was a ballast, and once it was a bulb.
I then bought decent 35W ballasts from Ebay for about 18 bucks to replace those 55Ws but kept the same bulbs. The bulbs and ballasts have lasted me through my one roadtrip to Florida with all night driving no problems.
Last month, I decided to upgrade to these fanless LED bulbs:

They work great. They are instantly bright since they are LED. No need for a ballast or anything. The best part is I can shove the little box and the wires all into the housing and put my dust cover back on. All you have to do to get the heatsink to work is to spread the leaves and flip them a bit. No need to cut your dust caps. They have lasted me during some pretty long night drives.
In terms of brightness and performance:
55W:
Pros - Brightest out of all of them and really lights up the road. Good light spread to the sides.
Cons - Unreliable as heck and won't last you a road trip, dies quickly on you, bulbs and ballasts. Have to drill a hole through the dust cover to wire to ballast. Need a relay kit.
35W:
Pros - Still brighter than halogens by a lot and still has a decently good spread of light to the sides.
Cons - Needs a relay kit. Needs to drill a hole through rubber dust cover.
LED fanless:
Pros: Just as bright as the 35W HIDs. No cutting necessary. Dust caps go back on. No ballast required. Instant on.
Cons: Comes in one color and it has a 5000K - 6000K look instead of a 4300K. The horizontal spread of the light is just like the stock halogen. (Since the LEDs use an LED facing up and down but none to the sides).
Out of all the solutions. I really like the LED fanless solution. Had I found out about it sooner, I probably would have never bought those HIDs. Hopefully these LEDs were built correctly so the voltage spikes of the car doesn't make these LEDs flicker in the future. I'll be going to Florida with these bulbs and I'm hoping it'll last a 16 hour drive one way. Only time can tell.
EDIT: After having two separate LED kits, I bought a pair of 4,800 lumens. The brightness is there, but the throw isn't as far as an HID would go.
