The first thing I check is the color temperature, because white lights are never just white. Hold one up and it either leans toward blue and clinical, the kind of light that makes your kitchen feel like a hospital corridor at ten at night, or it leans warm, closer to candlelight, and that's the difference between a string of lights looking cheap and looking like you meant it.
Warm white is the easiest shade to live with, almost every time. It sits closer to 2700 kelvin if the packaging bothers to tell you, and it flatters wood, brick, skin, pretty much everything in a real house that isn't a showroom. True white or daylight white has its place over a mirror or a desk where you need actual task light, but strung around a window or along a shelf it tends to go cold fast, especially once the bulb is a year old and starting to shift. If you've got nothing yet, start with a warm white string on a simple cord, copper or clear, nothing fancy, and use it somewhere small first, a mantel or a bookshelf, before you commit to wrapping an entire room in it. You'll know within a week if the tone works for your space or if it's fighting your lamps.
Measuring matters more than people expect. For a window, you want the string long enough to drape with a little slack, not pulled taut like a clothesline, so measure the width and add at least a third again for the loops. For a staircase or a mantel, count the lights per foot rather than just the total length, because a string that's technically long enough can still look thin and sparse if the bulb spacing is wide. The mistake I see most is buying one string to do a job that needs three, and ending up with something that looks like an afterthought instead of intentional. Check the plug placement too, a cord that enters in the middle instead of the end changes how it drapes completely. As for lasting, the cheap ones go dim and patchy within a winter or two, one section dies and the rest limp along, while a decent set with a proper warm white LED and a sealed casing will survive a move, a damp basement storage box, and getting tangled in a bin for eleven months without complaint.
So before I buy, I hold it up against the wall and ask myself: does this look like warm light in my house, or does it look like a shop display I'm about to bring home by mistake?
