I'll be replacing these sliding windows soon but I'm having a hard time deciding on what to replace them with. I found some andersen sliders of the same size for about $800 a window.

I'm also tempted to get two single hung windows mulled or even casement windows of the same dimensions but instead of a single window it'd be two that make up the casement windows like the one I attached.

Any suggestions for my home layout would be appreciated.

The old windows are about 20 years old, single pane, and super leaky air wise.
