Not a matter of hate---there are just better bolt rifles out there. Kind of like a Chevy 350 engine and a Honda 2.0 liter. Easy to find aftermarket parts to do whatever you want to one. There is a reason for that btw...
Yes, there are better bolt action rifles out there. Most of those cost 3-times what I paid for my first-generation A-Bolt Stainless Stalker. Within the same price range Brownings are among the best available. They tend to shoot better than out-of-the-box Remington 700s and look much nicer than Savages. A Sako 85 is a better rifle than the Browning A-Bolt, but not by much and the cost of the Sako is much more. The same can be said for a Weatherby Mark-V, nicer but more money. Yes, the custom & semi-custom rifles now available should beat any production rifle, but that comes with a price.
I have & have had bolt-rifles of many makes so I'm not one of the people who say the first rifle I bought is the only brand I'll ever own...
The "SLAM" Browning takes on sites like this one is these rifles are normally not the optimal basis for a custom build. Barrels are loc-tited on and custom stocks to fit are few & far between. A 3-lug bolt can be more difficult to get "perfect" than a 2-lugged bolt (but when it's right, it's a thing of beauty). That said, the custom builds based on A-Bolt actions I've seen have been rifles I would love to own.
