What is the best home security system for modern homes?

I’m looking to upgrade my home’s security and would love recommendations on the best home security system available. With so many options out there, it’s hard to choose. Ideally, I want something that integrates well with smart home devices and offers robust internet features, like remote monitoring and real-time alerts. What systems have you found to be reliable and effective? Any insights on setup, costs, and ease of use would be greatly appreciated.
