IKEA is a two-edged sword, IMO. Because they mass produce, their prices are good, their consistency is great, their quality is high, they keep up with style trends, and their staff is reasonably well trained, because they do so many kitchens. There's no arguing that you get a lot of bang for your buck there.
BUT, it will always look like an IKEA kitchen. I look at a LOT of houses and I can usually spot an IKEA kitchen without even opening a cabinet door. I suspect that matters more if you're doing a remodel with the intent to sell. If you like the look and you're creating your forever home, I'd definitely strongly consider IKEA. I might put some creative thought in to make it a little less cookie cutter/trendy. For example, source the hardware somewhere else or be creative in how you plan the space, don't use the obvious IKEA accessories like those little bars with hanging buckets, utensils, or both.
A functioning, solidly built, efficient kitchen (especially if your current one is not) is definitely money well spent.
