Pixieset is great for making simple portfolio websites as well as delivering photos and taking bookings
Photography
A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
Format.com is incredible. It's made for photographers. You can make incredibly simple yet professional looking websites with absolutely zero knowledge. It does it all for you. It's fully worth the investment if you want to look professional and don't have time to make a website.
I like SmugMug for ease of use and delivery and the price can’t be beat.
Are you a subscriber to Adobe Creative Cloud? If so, the Behance website is part of the deal. There is also Adobe Portfolio. For a portfolio these two should suffice. I've used Smugmug for 15 years and Zenfolio for 7 years, but I prefer Behance for portfolio work.
If you're subscribed to Adobe creative cloud for Lightroom/Photoshop, Adobe portfolio is included.
If you're not subscribed or else you need more/different features for whatever reason, there are dozens of services to have a look at. Smugmug, Zenfolio, Squarespace, Photoshelter, Wix, Format, Wordpress...
There's no best/worst, it's just a question of what you like and what suits your needs.
You're own website. And there are tons of platforms to host it on.
Adobe Portfolio, Zenfolio, SquareSpace, Format, WordPress,...
I use Photofolio.com it is a portfolio website system developed by a magazine photo editor specifically for photographers.
