Stuart,
Windows Defender, the built-in one.
[I should use the new name Windows Security really].
The third-party offerings are only worthwhile if you happen to need the additional facilities they provide [such as the VPN facility you've seen mentioned in earlier posts].
The level of malware protection provided by Windows Defender is as good as anybody else's; it really is just their extra facilities that distinguish the third-party ones.
See www.avtest.org for comparations of protection level.
About five years ago, I worked my way round trying these for about a month or more each - Bitdefender, Kaspersky, McAfee, Norton. I never found a single reason to keep any of them.
All the best,
Denis
