best water heaters 2026 for a normal 2 bath home?

homeowner here trying to plan a water heater replacement before my current one fails. It’s a gas tank unit around 11 years old and lately it’s been louder than usual and the hot water doesn’t last as long, especially when showers run back to back. I’m trying to narrow down what type of unit I should be looking to buy for a typical house, not asking about pricing or quotes, just what kind of product actually makes sense to install.

• For a normal 2 bath home, what type of water heater should I be looking at right now?
• Are tank units still the safer choice or are tankless and heat pump models worth considering?
• What size or capacity should I be aiming for to avoid running out of hot water?
• Are there common reliability issues with newer units that I should avoid when choosing one?

TIA fot the help!!
