Contrary to the common man belief that 'Windows is very insecure', Microsoft has been very proactive in security. Apple iOS has a great deal of security too, it is described in its building from scratch in the iOS security document. Here are the few points I found great for mention. Here's a small video which has the debate on.

Have made great changes in terms of security eg. Security Development Lifecycle (SDL), considered Industry model
Bluepill attack ineffective in Windows 8 - due to installation of an empty hypervisor and alert on other hypervisor installation
Windows 8 x64 also removed backward support for documents-caused as source for bugs
UEFI, an alternative for BIOS which overcomes certain BIOS limitations eg.prevents Bootkit attacks
Secure Boot verifies Windows OS is not compromised
Pwn2Own (hacker competition) - Lately Windows has been the hardest to compromise
Windows is doing great at preventing zero-day attacks& verifying kernel modifications
Jail breaking has become very difficult
Admin rights reserved, so attackers cannot exploit privilege escalations
Admin rights reserved is also a great step for enterprise security as Apple security expert can be trusted more than any common user
Isolation of applications- apps are signed,verified and sandboxed
Secure Boot Chain - allows iOS to run on validates Apple devices
Secure Enclave(A7 or later Aseries) - allows data integration even if Kernel is compromised
UID(unique ID) & GID(group ID)-i.e. encryption AES 256 keys fused in application processor, not allowing any software/firmware to read it directly
Keychain Data Protection
FIPS 140-2, iOS 8 cryptographic modules (U.S. compliance validation) that will validate integrity of Apple apps and third party apps properly using iOS cryptography services.
* We have mentioned a few, this is a suggestive list not binding, there are various other features.
