I'm a fan of lighters with a right-angle candle flame. The problem is finding one that's reliable. The reason I like such lighters is because the soft candle flame permits the greatest control in lighting up the way you want to, rather than adjusting your lighting style to the technology.
Though I usually use cheap plastic Bic lighters, I don't consider them the best pipe lighters for this reason. Bic lighters are probably your best bet because they're so ubiquitous, reliable and cheap. However, most of them lack a flame adjustment, and the flame comes out a bit too strong, which risks charring the briar and forces adjustments to the way you touch the fire to the leafs and draw the flame.
I've never used the Corona Old Boy, but I have one practically identical in style and function. I like the flame, but I find the flint aggravating: the sparking flywheel usually requires far more pressure than a simple thumb flick, the flints wear down quickly (and it's tricky even assessing this), replacing flints is a pain, and flint replacements are shockingly exorbitant (at least in Canada: $5 for a simple little flint!). The flywheel that adjusts the flame length is very nice, but it doesn't make up for its detriments to me. Every so often I'll take it out and try to make a go of it, but it soon ends up a frustrating experience, which defeats the whole point of using lighters as a convenience.
I recently purchased a Xikar Resource Pipe Lighter. (I wanted the Vector Colt but I couldn't find it anywhere I intended to shop, so I settled for the Xikar.) It comes with a built-in tamper/poker/knife tool that's pretty crappy but would do in a pinch if you forget your regular tamper. It has an adjustable flame, but it's not a simple flywheel which makes it a pain to adjust, which is its biggest design drawback. It also won't light in the cold fresh air of a Canadian winter. Indeed, it's generally a bit temperamental and requires a certain touch to guarantee the spark will catch.
But I definitely favor electric lighters like this over flints like the Old Boy anyday.
After saying all this, matches are still probably the best light, even though it requires two hands and has other inconveniences.
Personally, I like the convenience of a lighter, and even though I haven't yet found the perfect one, the electric one will suffice just fine for me for now.
Whatever you use, though, I agree with Bob -- always use soft flame lighters on your pipes (unless you have mastered the Frank method, grasshopper).
There's nothing quite like tobacco: it's the passion of decent folk, and whoever lives without tobacco doesn't deserve to live.
