DisplayPort to HDMI or VGA or HDMI to VGA adapter?

Hi,

I have a MacBook Air and I need to use it with HDMI and VGA port.

I have to decide which adapter is the best purchase for having both the options (HDMI and VGA). Should I buy a DisplayPort to HDMI and DisplayPort to VGA adapter or a DP to HDMI and a HDMI to VGA adapter (to be used when I need it with the other adapter)?

Thank you
