Some things to remember, DLP projectors are typically half the size (Or less) than LCD projectors. (Although there are exceptions particularly in the low end range)
You will usually get more features (Full lens shift etc.) on LCD projectors for the same cost.
You get way more detail on a DLP due to the way it does 4K, plus you only have a single chip rather than 3 which can become misaligned.
WARNING: Under NO circumstances buy a projector without trying first, as all have their positives and negatives, so you need to make sure the negatives don’t outweigh the positives for your viewing experience. (Everyone is different)
Have fun choosing, as there is no substitute to a projector and screen when it comes to the cinematic experience. (Also don’t skip on the sound system which is arguably more important to get the full immersive experience)
