Depends. When I got mine, they didn't have a great view side-to-side. I noticed this especially on turns. There is a very specific shape to the lights. OEM lights tend to scatter the light vs. projectors focus the beam. On the flip side, in some areas you get better light than OEM. You can compensate this though more upgrades:
1) Upgrade headlights to HID. The halogens are not that great that come with these. I've noticed a difference since upgrading to HID. Plan on spending about $80 on a kit.
2) If you have fogs, upgrade those to HID too. The fogs will scatter the light and fill in the spots the headlights don't reach. The factory bulbs are more for show. Plan on $35 for this kit.
Do those two things and you'll have better light than OEM and your car will look awesome. If you can only afford one kit at a time, do the fogs first. Also, most people said their Spyder headlights come misaligned. Plan on adjusting these so you're not blinding people your first time out. My beam is between the trunk and taillights for most cars.
The halos are essentially an acrylic ring with an LED that projects into it. Kind of like a fiber optic cable in a ring. If you're looking for something that's bright in day-time then this is not for you. It does look great dawn, dusk, and night though. You can see them during the day but they are not as bright as an LED ring or CCFL. I didn't go that route because of costs and complexity of the install. You have to put your headlights in an oven to separate the lenses.
Good Luck. Let us know what you decide on.
