I'd rather see you keep Barkov over Giroux...
Giroux also holds more name value (for now) over Barkov.
I'd offer Giroux, Gibson, Connor for Talbot & D. Strome.
I'd keep Ho-Sang, he's the only one of the three that looks to be in the NHL for sure next season. It appears to be a stronger offer from you, but it allows you to get the prospect upgrade to Strome & keep the higher ceiling player - Barkov.
