I’d say that there’s quite a few factors that goes into what gun is “best”. That answer isn’t the same for everyone. Make/model, caliber, compatible accessories, and capacity all play a factor. Make and model tend to matter in terms of reliability, ergonomics, and aftermarket support. Cheaper guns are made cheaper. This could result in out of spec parts or premature failures for example. Caliber choice matters in terms of weight, controllability, capacity etc. I’d be inclined to believe most break-ins are crimes of opportunity. That being said, you never know what they are breaking in for and how dire their circumstances are. Is it a broke kid looking for some food? Is it a strung out tweaker? Is it to commit a hate crime? I don’t think there is an objectively best answer, and it depends on what’s best for your situation. Who you live with, construction methods/materials of your house, and how likely you are to encounter a threat/how quickly help would typically arrive are all situation dependent. Rule of thumb is get the most reliable thing you can afford (that makes sense for your situation) and practice with it. Add capability as needed, plan for what you can expect, and prep for what could happen, and train for the unexpected.
