#1 HOUSE
This was #1. When developing Siege, it's clear to see this was the first map they had created. Therefore this oozes everything Siege, and R6 potentially stands for - CQC, an Urban setting, and a reliance on communication. Originally, where defenders were allowed outside, the construction site opposite the house was to be used as well.

#3 CHALET
Who doesn't love a snow map? This is a really well designed map which offers a balanced approach regardless of which tactic you play. Go from above, or below or enter straight in the main doors - all can pay off depending on the situation. And considering Siege's ethos is that every situation can play out differently, this map does exactly that. Looks gorgeous at night too!
#4 PRESIDENTIAL PLANE
CLASSIC FUCKING SIEGE. Even though it's close and tight, there's also long hallways that make sure gameplay variety is still possible. Glaz has become such a popular choice on this one too now that he can penetrate through the windows! This is a 'Hollywood' Map that is one of my personal favourites. When it comes up in the playlist - you definitely get excited!
#5 CLUBHOUSE
#6 BANK
#7 BORDER
Year 1 Season 2 Dustline DLC Map. I am always torn between this one, sometimes it's nice, but sometimes I know there's a lot of the map which isn't used for most game modes so the design could have been better. But paired with Blackbeard's shield, there are some great opportunities for some aggressive window pushes!
#8 KAFE DOSTOYEVSKY
#9 HEREFORD BASE
Now I am British. so this map is cool for me. A military fun zone which I really enjoy. This is one of my favourite maps in the game. It can be quite confusing when some floors look the same - it's like a house of mirrors, and that's fun right? You can use any sort of weapon or operator on this map, it is so versatile.
#10 CONSULATE
#11 SKYSCRAPER
Year 1 Season 4 DLC Map. Not one of my favourites at all, I won't lie. And I think the community will agree with me on this one. What I can say though, is that it's totally different to every other Siege map. This could be its problem - that it sticks out like a sore thumb. But definitely gets +1 for individuality.
#12 COASTLINE
#13 KANAL
#14 FAVELA
Destruction. Year 1 Season 3 DLC map. This has torn the community big time; some love it, some hate it. It has the highest destructibility rate; which as a defender always make you feel vulnerable. There's so many levels and rooms, this is a playground map for me where you can have some great plays. Using Glaz/Buck on this map is recommended just so you can f**k shit up!
#15 YACHT
#16 Tower
#17 Theme Park
Not too scary at day. But when you play this map at night, it is by far the creepiest, eeriest Rainbow Six: Siege map to date! The Ferris wheel even gives of a kinda Chernobyl vibe. What makes this map great, however, is the total differences between objective locations. They require a unique approach to each round! All aboard the ghost train, guys!
#18 BARTLETT UNIVERSITY
Brought to us as an extra map during the end of Year 1. Bartlett University was including in the final multiplayer 'Situation' entitled 'Article 13'. This is the closest we got to a story mode for R6: Siege. The situation map had a thick yellow smog across the map due to a chemical gas attack on the university. Players wore gas masks which does make you think of how they could bring this in to online gameplay somehow? Could be a good combat against smoke!
Anyway, for the online map, the smoke was removed and faced some slight redesigns to better suit online play. Not proved too popular since release, but hey - it was an extra map!
