ULTRASPARC vs ARMv7 (Sun Netra T1 vs Orange PI ONE) from ONLY a security point of view

[Глеб Рахмановский]

 
Dear Gurus,
Please let me know, are there any advantages of UltraSparc IIe over Cortex A7 
AllWinner H3 for a secure communication host ignoring a factor of power 
efficiency, size and loud noise?
IMHO the only feature OpenBSD can benefit from UltraSparc is StackGhost ?
