NHK released their final Ultraman poll results! They posted 200 Kaiju results but I'll only post the top 15 below to keep it short. You can browse the rest here, though!

8: Eleking

5: King Joe
4: Gomora
3: Baltan
2: Juggler
1: Zetton

Interesting to see Z this high. Might still be some form of new car smell, I'm curious to see if the popularity holds up. I sure wouldn't mind, I love Z.

As for Kaiju, I'm not surprised and similarly happy to see Jamila in the Top 10. For a monster that had one single appearance, it sure left an impact. Understandably so, it was an excellent monster with a fantastic story.

Plus, Juggler! Might again be due to his recent resurgence in Z, but number 2? Absolutely deserved but a little bit shocking that he was only beaten by Zetton while surpassing classics like Baltan and Gomora.

people really love Tiga, huh

Tregear is a kaiju?

The list counted all 'evil' Ultras in the Kaiju/Aliens list. So Belial, Tregear, Evil Tiga, Orb Dark, any imitation Ultras, edge-cases like the Dark Giants; even some that became allies later like Trigger Dark. Despite the latter, Agul and Justice are still on the Ultra Heroes list.

Here’s the list in terms of mecha.

20: Space Pendragon (Zap Spacy)
19: MAT Gyro (MAT)
18: GUTS Falcon (GUTS-Select)
17: Magma Riser (Ultra Guard)
16: Artdessei (GUTS)
15: GUYS Gun Phoenix (Crew GUYS)
14: MAT Bihaikle (MAT)
13: Special Airborne Unit 4: Ultroid Zero (Storage)
12: XIG Fighter EX (XIG)
11: Hyper Strike Chester (Night Raiders)
10: MAT Arrow No. 1 (MAT)
9: Nursedessei (GUTS-Select)
8: GUTS Eagle (Super GUTS)
7: Gun Phoenix Striker (Crew Guys)
6: Jet Beetle (SSSP)
5: Special Airborne Unit 3: King Joe Storage Custom (Storage)
4: GUTS Wing No. 1 (GUTS)
3: A Pointer (Ultra Guard/Earth Defence Force)
2: Ultra Hawk No. 1 (Ultra Security Force)
1: Special Airborne Unit No. 1: Sevenger (Storage)

Also, the last 5 on the top 20 monsters are If, Dada, Bemstar, Evil Tiga and Tyrant.

The best boy Sevenger coming up on top.

You love to see it.

If Shin Ultraman had any influence on this poll, I completely understand the Kaiju rankings. You'll see!

I gotta be like, the only person not completely in love with Sevenger

Sevenger is everything great about Tokusatsu.
