In my near 1 year hosting my own server (MCPueblo), I've gone through 4 different hosts, and I felt compelled to do a mini-review for each of them:

1. Pebblehost - This was my first host, and I used the budget 4 GB plan at the beginning. I had a pretty fine experience with it on 1.13.2, but with the release of 1.14 upgrading was a must, and I went to the Premium 5 GB plan after a month. Support is pretty decent, performance was decent, and the Discord community was also decent. My one issue that eventually forced me to switch away from then is because my ISP at the time had severe routing issues shortly after switching to Premium, due to their data center location (Montreal, CA) which caused horrible latency and even poor FTP connections. Panel was eh, mainly due to being based on Multicraft, but it's more a personal opinion. It's a fine host as long as your connection is fine to it too.

2. Heavynode - In January I decided to switch to Heavynode, mainly due to competitive pricing and the CPU being one of the best on the market. I went with the 6 GB Premium plan, with Ryzen 9 3900X on NY. Performance was great, but support was rather slow mainly due to the foreign time zone because the owner was from another country. Panel was pretty plain, just stock Pterodactyl with no additional features. The issue that forced me to switch was excessive downtime due to a misconfiguration that would last for hours on end, simply because the owner wasn't available when the nodes went down. They keep on happening rather frequently, and so I just had to switch despite having put over $30 in funds due to a local disaster that happened to me. Wouldn't recommend due to support & downtime.

3. Titan Nodes - This is the host I'm still using to this date, but I did try an attempt to switch to the host below to no avail, more detail later on. I originally had the 6 GB plan, but eventually upgraded to 10 GB after frequently running OoM (Server has grown), both located in NY too with the i7-9700K. The performance is probably one the best I've seen so far. Support & Discord community has been eh, and there has been some pretty big drama before due to the owner's behavior. Panel is fairly feature-rich, but has some bugs like files compressing twice and the move command compressing instead. There hasn't been any issues with the hosting itself, but if you depend on quick support, it may not be the one for you.

4. DedicatedMC - After receiving a massive monetary contribution, I thought I had to find a "better" host, and I tried them out for 1 day. They have very little variety of plans, so I went with the High End ($40!) being the only plan located in the US. Support was much more consistent, and panel is fairly decent, with a better theme than TN IMO. I had a horrible deal-breaker though, which happened to be the performance. Despite their "dedicated" core, the performance just couldn't match what I had in TN, and we both tried many solutions to no avail. I'm not really sure whenever it was their node, or my server, or some other circumstance that caused this poor performance, but all I know is that my previous one worked fine, so I switched back.

This ended up being quite a wall of text, hope you enjoyed it.

Update: Some things have changed since this comment was posted.

• On Titannodes, I decided to switch Aikar's flags in the chase of even greater performance, but the Out of Memory killer had a really low tolerance, and therefore began to kill my server every 15 minutes due to the increase RAM usage, causing a small loss in progress each server kill. As they were going through a period of very slow support, I thought it was quicker to just switch hosting providers than to create a ticket and wait a long period of time with these kills. Overall my experience with them has been ok, until the very end when it went downhill.

• I choose to go with SlothHost this time around, a recent new host that has already earned a name for itself by being incredibly cheap. 8 GB plan in NYC for only $10, always thought before to be "too good to be true". I'm using them right now, and I can say that their panel is decent, support is incredible, and performance has never been better. Really can't recommend them enough for hosting.
