I've tested out surface pro, iPad, wacom cintiq etc. But I always come back to my intous.
Wacom is highly recommended because it's got a reputable history of making products tailored to the creative industry. Just like if you're after a gaming keyboard, a certain company will pop into your mind.
You will find that they are almost compatible with any creative softwares out there, and the stylus doesn't need battery or charging. It's light and it's chunky which is better to hold in the long run. The surface of the tablet is matte which imitates paper (for people who are transitioning from traditional to digital, this is great a addition). For people who like gloss, there's also an option for that too.
The company also has constant driver updates for the older tablets too, so the users don't feel neglected. They really take care of their customers. The price may scare you from the beginning. But I've had my intous for 5 years now and it's still been great, and works better than my Surface Pro 4. The diver is still being updated, I still haven't purchased nibs for it.
I spent $500Aud which lasted for 5 years so far and I use it a lot. So yeah, I personally prefer wacom products just really because they know what they're doing.
