Adjustables save space and money
A single pair of adjustables spans roughly 2.5 to 24kg or more, replacing a dozen fixed pairs that would cost several times as much and fill a wall. That is the right call for home training.
Buy adjustable dumbbells for a home gym on space and budget, fixed only if you have room and want fast, durable set changes.
For almost every home lifter, adjustable dumbbells win. One pair replaces a whole rack, costs far less than buying every increment, and fits in a corner. Choose fixed only if you have the space and cash for a full rack and want zero adjustment time between sets, which matters most for dropsets and heavy commercial use.

Fixed dumbbells change instantly and survive being dropped, which is why gyms use them. If you do a lot of dropsets or train explosively, the seconds saved and the durability can be worth the space.
Cheaper adjustables can be bulky, have a long handle, and dislike being dropped. Look for a compact plate stack and a reliable dial or pin, and set them down rather than dropping them.
