what are your opinion on Husqvarna 455 rancher i have one of those also have a stihl 028 wood boss

I've never used a 455 but my smaller sized saw is a husky 55 which is the model the 455 replaced.its a great saw and has alot of power for what it weighs. i ported the muffler and the cylinder on mine and threw some new rings on it and they can really keep up
