People are really worried about bumping huh? I've played with bump keys a fair bit and only ever managed to bump open basic cylinders with no security pins... I know for a fact it can be done but from personal experience I'd say it actually takes a great deal of practice to have any real success with it. Personally I'd be more worried about destructive entry and/or bypass, like pin_pusher said.
You need to be looking at your security as a whole; fancy locks alone aren't going to change much. I'll get to locks in a second, but first of all I have to say that mental deterrents are the best form of defense against a burglar... things that make them think it's not worth it so they look right over your house and move to the next. Remember they don't care about
your stuff - they care about stuff, period. They never touch locks unless they think they're easy to break or force open... and trust me, they'd much sooner break a window or kick the back door in than even consider fiddling with your locks. It's good to have a strong deadbolt of course, but the cylinder itself doesn't actually matter.
That is unless your doors are fitted with euro profiles, in which case you'll want a reinforced anti-snap cylinder. Only for the back door though, as long as the one in the front is flush fitting with the handle they won't look twice at it. Of course the one at the back should also be flush fitting to make things more difficult, but on top of a strong cylinder you'll want additional door closers/bolts just incase the cylinder is breached. If they actually get this far they'll try and force the door open and if they're big enough they might just succeed... so you need to focus on not letting them get to this point in the first place.
Thankfully it doesn't take much to spook someone into moving along, your house is just one of many and the slightest chance of being seen/heard is all it takes. Good lighting and getting rid of hedges and fences which provide cover is your biggest weapon, believe it or not. The back/side entrance is the most widely chosen and if these entrances are out in the open they're gonna look for somewhere there is more ample cover. If this isn't an option, block off your back garden with a gate, lock it from the inside with strong bolts and put something on top of it so it can't be climbed over. Stick a decent padlock on the inside aswell so that even if they do manage to get in they're forced to leave through the front door or climb back over with whatever it is they take.
Fancy locks aren't a match for good overall security.
