From my point of view - for 5.56mm calibre semi-autos:
Best value for money, in terms of reliability, durability, support, and replacement components: IWI Tavor X95
Highest Quality: B&T APC 223-SA
"One step up" Tier of Quality: Bren 2 NR
Lightest, best suited for CQB: Bren 2 8" barrel
Best Canadian 5.56 rifle in the $2000-2500 range: Crusader Templar (also heaviest

)
Best Canadian 5.56 rifle in the $2500-3500 range: Sterling Arms R18 MkII - if Lockhart Tactical works out its BCG issues, the Lockhart Tactical Raven 5.56
Best Canadian 5.56 rifle in the $1500-2000 range: BCL Siberian SRV2
Best Canadian 5.56 rifle value for money: Crusader Templar, or Lockhart Tactical Raven if BCG gets fixed
If you want a rifle that will shoot well, is very reliable and durable and doesn't cost an arm and a leg, IWI X95 $2400 (sale)-2750 (typical)
If you want to support Canadian firearms manufacturers and are willing to put up with some QA/QC issues, buy a Crusader Templar ($2000-2250) or a Lockhart Tactical Raven 5.56 ($2250-2700 depending on options)
If you want to spend a little more - Bren 2 ($3000-3500 range)
If money is no object and you want the best quality available, B&T APC 223-SA ($5000+)
If you are really strapped for cash and must have a 5.56 rifle, WK180C Gen 2 ($1500), but replace the gas valve and really read up on the mods you have to do to prevent piston breakage.
If you are strapped for cash and don't mind 7.62x39, the WK181 ($1500) is looking promising - much more reliable than any of the other AR-180-based Canadian designs so far (10,000 rounds tested through CFET)
