Understanding the Impact of EIP-1559 on Gas Fees and Transaction Processing

I've been closely following the developments in the crypto space, and the recent implementation of Ethereum Improvement Proposal (EIP) 1559 caught my attention. While I understand the basics, I'm curious about the real-world implications, especially in terms of gas fees and transaction processing.

Could someone shed light on how EIP-1559 affects gas fees and what changes it brings to the transaction confirmation process? I'm particularly interested in understanding whether it has led to more predictable fees and how it might impact various types of transactions.

Additionally, if there are any best practices or strategies for users in this post-EIP-1559 era, I'd love to hear about them.
