From my experience, Reels usually get much more reach than normal image or text posts. But there's something I've learned, getting a lot of views doesn't necessarily mean getting new followers. I've had Reels with thousands of views and practically no new followers. I think it's better to combine both.
Also try joining groups related to your niche, or groups where you think people might be interested in your content.
And don't just limit yourself to posting, you also need to comment on other posts, interact with other pages and reply to people. That helps a lot, don't focus only on the views.
