Help me pick the best one ?

Hello everyone, can you help me make a sound decision.. which one of these is the best bang for buck

• S&W Volunteer XV for $460 after rebate
• S&W M&P Sport III for $540 after rebate
• Ruger 556 for $510

Everywhere I check it seems like XV is superior compared to other two but it doesn’t have much reviews online.. can you all please help

My intended use is range toy and home defence
